Long-Lived Particles
- Felix Kling (SLAC)
We have investigated the search sensitivity to long lived light neutralinos, with masses below a few GeV down to 10s of MeV, at various forward detectors. The can be produced at the LHC via rare decays of standard mesons or via rare Z-boson decays. The neutralinos decay to a lighter meson plus a charged lepton, which can be observed. We have studied a large set of proposed experiments: ANUBIS;...
We consider strategies for using new datasets to probe
scenarios in which light right-handed SM fermions couple
to a new gauge group, $U(1)_{T3R}$. This scenario
provides a natural explanation for the light flavor
sector scale, and a motivation for sub-GeV dark matter.
There is parameter space which is currently allowed, but
we find that much of it can be probed...
FASER is one of the promising experiments which search for long-lived particles in beyond standard models.
In this paper, we focus on dark photon associating with an additional U(1) gauge symmetry, and also a scalar boson
breaking this U(1) gauge symmetry.
We study the sensitivity to the dark photon originated from U(1)-breaking scalar decays.
We find that sizable number of the dark...
We study the prospects of a displaced-vertex search of sterile neutrinos at the Large Hadron Collider (LHC) in the framework of the neutrino-extended Standard Model Effective Field Theory. The production and decay of sterile neutrinos can proceed via the standard active-sterile neutrino mixing in the weak current, as well as via higher-dimensional operators arising from potentially new,...
In this talk I will discuss the connection of different neutrino mass models with long-lived particles (LLPs). We will also discuss the prospects of the LHC and several recent experimental proposals to search for these LLPs.
