Light long-lived particles at the FCC-hh with the proposal for a dedicated forward detector FOREHUNT and a transverse detector DELIGHT

| Physical Review B
In this paper, we propose a dedicated forward detector, FOREHUNT (FORward Experiment for HUNdred TeV), for 100 TeV FCC-hh for the detection of light long-lived particles (LLP) coming from B-meson decay. We calculate the signal acceptance as a function of mass and proper decay length of the LLP for 100 TeV and interpret our result in terms of model parameters for models of dark Higgs scalar and heavy neutral leptons.

Long-lived NLSP in the NMSSM

| Physical Review B
We analyze the scenario within the next to minimal supersymmetric Standard Model, where the lightest supersymmetric particle is singlinolike neutralino. By systematically considering various possible admixtures in the electroweakino sector, we classify regions of parameter space where the next to lightest supersymmetric particle is a long-lived electroweakino while remaining consistent with constraints from flavor physics, dark matter direct detection, and collider data.

Is Light Neutralino Thermal Dark Matter in the Phenomenological Minimal Supersymmetric Standard Model Ruled Out?

|
By Geneviève Belanger, Rohini M. Godbole, Rahool Kumar Barman, Biplob Bhattacherjee
| Physical Review B
Abstract We explore the parameter space of the phenomenological minimal supersymmetric standard model with a light neutralino thermal dark matter (mχ˜10≤mh/2) that is consistent with current collider and astrophysical constraints. We consider both positive and negative values of the higgsino mass parameter (μ).
