High Energy Physics - Experiment
We present a precision measurement of the branching fraction of the rare decay $J/ψ\toμ^+μ^-μ^+μ^-$, and a search for a new gauge boson $Z^{\prime}$ that couples only to the second and third lepton generations, using a data sample of $(8998 \pm 39) \times 10^6$ $J/ψ$ events collected by the BESIII detector.
High Energy Physics - Experiment
By analyzing $(2.712\pm0.014)\times10^9$ $ψ(3686)$ events collected by the BESIII detector, we report the first experimental study of the decays $χ_{cJ}\to p K^- K^- \bar Ξ^{+}+c.c.~(J=0,1,2)$.
High Energy Physics - Experiment
Using a sample of $(2712.4 \pm 14.3) \times 10^6$ $ψ(3686)$ events collected with the BESIII detector, we perform a partial wave analysis of the decay $ψ(3686)\toπ^{+}π^{-}η$ with the $π^{+}π^{-}$ invariant mass in the $ρ(770)^0$ mass region, [0.3, 2.2] $\mathrm{GeV}/c^2$. The cross section line-shape around the $ψ(3686)$ resonance is measured using energy-scan data sets, enabling the estimation of continuum contribution and its interference with the $ψ(3686)$ resonance.
High Energy Physics - Experiment
Based on a sample of $(2712.4 \pm 14.3) \times 10^6$ $ψ(3686)$ events collected with the BESIII detector at the BEPCII collider, we report the first observation of the decays $ψ(3686)\to\bar{p} K^{+} Σ^{*}(1385)^{0}+c.c.$ and $ψ(3686)\to\bar{p} K^{*}(892)^{0} Σ^{+} + c.c.$.
High Energy Physics - Experiment
Using a data sample of $(10087 \pm 44) \times 10^{6} J/ψ$ events collected with the BESIII detector, we search for the rare decay $η^{\prime}\to 3γ$ via the process $J/ψ\toγη^{\prime}$. No significant signal is observed and an upper limit on the branching fraction of $η^{\prime}\to 3γ$ is set at $\mathcal{B}(η^{\prime}\to 3γ) < 2.25\times 10^{-5}$ at the 90\% confidence level. This result improves the previous upper limit by more than a factor of four.
High Energy Physics - Experiment
Using $e^+e^-$ collision data collected by the BESIII detector at center-of-mass energies from $3.80$ to $4.95~\text{GeV}$, the inclusive production cross sections of open-charm mesons, $σ(e^{+}e^{-}\to D^{0}/D^{+}/D_{s}^{+}+X)$, are measured by tagging a $D^0$, $D^+$, or $D_s^+$ meson, where $X$ denotes any accompanying particles. Open-charm production dominates the total hadronic yield above threshold.

Salernitana, dubbio tra Vitale e Varela Djamanca
28 La Salernitana va a caccia del poker. Reduce da tre vittorie consecutive tra le mura amiche, la squadra di mister Cosmi si affida ancora al fattore Arechi per scacciare… i cattivi pensieri. Il pareggio a reti bianche di Casarano ha fatto storcere il muso ai più e, più in generale, la mancanza di intraprendenza mostrata dai granata in particolare nelle gare esterne è un elemento su cui anche la società sta effettuando le sue valutazioni.

Using $e^+e^-$ collision data collected by the BESIII detector at BEPCII corresponding to a total integrated luminosity of 44.6 $\rm fb^{-1}$, we present the first measurement of the Born cross sections for the process $e^+e^-\to pK^{-}\barΣ^{0}$ + c.c. at fifty-six center-of-mass energies between 3.51 and 4.95~GeV.
High Energy Physics - Experiment
We perform a simultaneous amplitude analysis of the decays $D^0 \to K_{\text{S}}^{0}π^{+}π^{-}$ and $D^0 \to K_{\text{L}}^{0}π^{+}π^{-}$ using an $e^+e^-$ collision data sample, corresponding to an integrated luminosity of $20.3\,\text{fb}^{-1}$, collected at the centre-of-mass energy of $3.773\,\text{GeV}$ with the BESIII detector.
High Energy Physics - Experiment
Using a data sample of $(2712.4\pm14.4)\times 10^{6}$ $ψ(3686)$ events collected with the BESIII detector, we report a high-precision study of the $π^{0}π^{0}$ mass spectrum from $ψ(3686)\rightarrowπ^{0}π^{0}J/ψ$ decays. The enhancement previously observed near the $ππ$ mass threshold in the $π^+π^-$ channel is confirmed, with a statistical significance exceeding 10$σ$.
Salernitana, novità in arrivo per la sfida di Casarano
15 Capuano, Villa e Lescano in campo dal primo minuto al posto di Anastasio, Longobardi e La Gumina: sono queste le novità di formazione che mister Cosmi ha in mente per la sfida di domenica al Capozza. Per cercare di mettere alle corde un Casarano in netta difficoltà, il tecnico granata sta ragionando sui correttivi da apportare all’undici titolare da mandare in campo nella prossima giornata di campionato.
High Energy Physics - Experiment
By analyzing $(2712.4\pm14.3)\times10^6$ $ψ(3686)$ events collected with the BESIII detector operating at the BEPCII collider, we report the first observation of $χ_{cJ}\to ΛK^0_S\bar Ξ^0 + c.c.$ ($J=0,1,2$) with significances greater than $10σ$, including systematic uncertainties, and improved measurements of $χ_{cJ}\to ΛK^-\bar Ξ^+ + c.c.$ The branching fractions of these decays are determined to be $\mathcal{B}(χ_{c0}\to ΛK^0_S\bar Ξ^0+c.c.)=(1.13\pm0.13\pm0.13)\times10^{-4}$,...
#680: Geen gedegen onderzoek, geen ontneming
#680: Geen gedegen onderzoek, geen ontneming Eerder dit jaar behandelden we in Vaklunch #655 de uitspraak van de rechtbank Den Haag waarin het Openbaar Ministerie niet-ontvankelijk werd verklaard in de ontnemingsvordering, omdat de originele administratie grotendeels was vernietigd. Zonder die administratie was volgens de rechtbank immers niet te controleren welke inkomsten legaal waren en welke wederrechtelijk. De rechtbank Noord-Nederland trekt die lijn nu door.
Astrophysics > High Energy Astrophysical Phenomena
We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at $z = 2.0155$. We use integral-field Keck-II/KCWI spectroscopy to obtain rest-frame ultraviolet spectra spanning $11$ to $61$ days after maximum light. We use Pan-STARRS photometry to constrain the brightest image's magnification, finding $μ_A=19.4\pm1.6$, a factor of $\sim$2-4 higher than mass-modeling estimates.

La Salernitana si prepara per ospitare un Bari in salute
21 Una Salernitana parsa in difficoltà domenica riceverà la visita di una delle squadre più in forma del girone, il Bari. Dopo la sconfitta di Barletta, i pugliesi hanno piazzato 6 risultati utili di fila (tra Coppa e Campionato), agguantando la vetta della classifica in coabitazione col Potenza a quota 16 punti. Il Bari è lì dove tutti si aspettavano che fosse sin dall’estate.

Wide-field surveys now report thousands of transients per month, while spectra are obtained for only a few per cent of them. We present DETECT (DESI--Transient Event Cross-matching Tool), a pipeline that turns each Transient Name Server (TNS) alert into a distance-informed candidate within an hour by placing it in the context of the Dark Energy Spectroscopic Instrument (DESI) archive.

Using $2712.4 \pm 14.3$ million $ψ(3686)$ events collected with the BESIII detector, the $Λ\barΛ$ system produced in $ψ(3686)$ radiative decays is studied. A model-independent partial wave analysis reveals a significant threshold enhancement structure dominated by the $^1S_0$ and $^3P_0$ partial waves, corresponding to $J^{PC} = 0^{-+}$ and $0^{++}$, respectively.

Seductive or deceiving? A focus group study on perspectives and expectations of consumers on meat alternative labeling practices
Abstract Introduction: As the global food system seeks sustainable solutions to address the challenges of climate change and a growing population, meat alternatives have emerged as a promising option for reducing the environmental impact of meat production. Over the past decade, their promotion has increased, while debates persist regarding the use of meat-related terminology on these products and its potential to confuse or mislead consumers.

Cosmi disegna la Salernitana anti – Sorrento
92 Il giorno del debutto in campionato si avvicina e mister Cosmi sta mettendo tutti alla prova per decidere a chi affidarsi per la prima all’Arechi con il Sorrento. Il tecnico, com’è noto, sta facendo i conti con le diverse assenze, legate ad infortuni e squalifiche. Al netto dei giocatori in infermeria (Heinz, de Boer e Bevilacqua), per l’esordio di lunedì sera all’Arechi, la Salernitana deve fare a meno anche dei due squalificati, Tascone e Llano.
Salernitana, lesione per Heinz: lungo stop
53 L’infortunio di Jonas Heinz aveva generato fin da subito diverse preoccupazioni e già nei giorni scorsi si era intuito che i suoi tempi di recupero sarebbero stati piuttosto lunghi: adesso è arrivato anche il responso ufficiale dal notiziario della Salernitana. Il bollettino parla di “lesione di alto grado al legamento collaterale mediale del ginocchio destro”.
Cosmi, tra mercato e il campionato che incombe
17 Non solo cattivi pensieri, per mister Cosmi, in vista dell’esordio in campionato contro il Sorrento.

Salernitana, la possibile formazione in Coppa Italia
16 Di buon mattino, con inizio della seduta alle 8:45 per evitare le ore più calde della giornata, la Salernitana si allena al Mary Rosy in vista della gara di Coppa Italia di Serie C contro la Scafatese, fischio d’inizio dopodomani (a Ferragosto) alle ore 21 allo stadio Arechi. Serse Cosmi prova alcune soluzioni per decidere la formazione titolare da mandare in campo nella prima partita ufficiale della nuova stagione.

Microtopography screening to modulate the mitogenic effects of aqueous humor on human tenon fibroblasts
Abstract Background: Glaucoma is a leading cause of blindness, with elevated intraocular pressure being a primary risk factor due to the accumulation of aqueous humor in the anterior chamber. Aqueous humor is known to modulate the proliferation of surrounding fibroblasts, which may influence the long-term success of glaucoma drainage devices. This study investigates whether the mitogenic effects of aqueous humor can be modulated through the control of implant surface microtopography.
