Long-lived neutral fermions at the DUNE near detector
Julian Y. Günther, Jordy de Vries, Herbi K. Dreiner +2
At the Deep Underground Neutrino Experiment (DUNE), a proton beam hits a fixed target leading to large production rates of mesons. These mesons can decay and potentially provide a…
Heavy neutral leptons from kaons in effective field theory
Rebeca Beltrán, Julian Günther, Martin Hirsch +2
In the framework of the low-energy effective theory containing in addition to the Standard Model fields heavy neutral leptons (HNLs), we compute the decay rates of neutral and char…
The decay at Belle II and a massless bino in R-parity-violating supersymmetry
Zeren Simon Wang, Herbert K. Dreiner, Julian Y. Günther
Recently, \texttt{Belle II} announced evidence for the decay at the significance, and measured the corresponding decay branching ratio to be …
Probing the dipole portal to heavy neutral leptons via meson decays at the high-luminosity LHC
Daniele Barducci, Wei Liu, Arsenii Titov +2
We consider the dipole portal to sterile neutrinos, also called heavy neutral leptons (HNLs). The dipole interaction with the photon leads to HNL production in meson decays, as wel…
A C++ program for estimating detector sensitivities to long-lived particles: Displaced Decay Counter
Florian Domingo, Julian Günther, Jong Soo Kim +1
A series of far-detector programs have been proposed for operation at various interaction points of the Large Hadron Collider during the upcoming runs. Investigating the potential…
Recasting Bounds on Long-lived Heavy Neutral Leptons in Terms of a Light Supersymmetric R-parity Violating Neutralino
Herbi K. Dreiner, Dominik Köhler, Saurabh Nangia +2
In R-parity-violating (RPV) supersymmetric models, light neutralinos with masses from the GeV-scale down to even zero are still allowed by all laboratory constraints. They are furt…
