Colliders are not Testing Locality via Bell's Inequality nor Providing an Unconditional Proof of Entanglement

Steven A. Abel, Herbi K. Dreiner, Rhitaja Sengupta +1

Recently there has been an increased interest in possible tests of locality via Bell's inequalities, as well as separately tests of entanglement at colliders, in particular at the…

The ABC of RPV II: Classification of R-parity Violating Signatures from UDD Couplings and their Coverage at the LHC

Herbi K. Dreiner, Michael Hank, Yong Sheng Koay +5

We perform a detailed study of the current phenomenological status of baryon number violating operators within the framework of the -parity violating Minimal Supersymmetric Stan…

A Proposal for the Lohengrin Experiment to Search for Dark Sector Particles at the ELSA Accelerator

Philip Bechtle, Christian Bespin, Dominique Breton +23

We present a proposal for a future light dark matter search experiment at the Electron Stretcher Accelerator ELSA in Bonn: Lohengrin. It employs the fixed-target missing momentum b…

Probing light sterile neutrinos in left-right symmetric models with displaced vertices and neutrinoless double beta decay

Jordy de Vries, Herbi K. Dreiner, Jelle Groot +2

An investigation of relatively light (GeV-scale), long-lived right-handed neutrinos is performed within minimal left-right symmetric models using the neutrino-extended Standard Mod…

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…

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
