With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

The European Particle Physics Strategy Update (EPPSU) process takes a bottom-up
approach, whereby the community is first invited to submit proposals (also called inputs) for …

A bstract Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many
extensions of the Standard Model. These particles can, among other things, explain the …

A bstract The exploration of long-lived particles in the MeV-GeV region is a formidable task
but it may provide us a unique access to dark sectors. Fixed-target facilities with sufficiently …

A bstract Proton beam dump experiments are among the most promising strategies to
search for light and feebly interacting states such as axion-like particles (ALPs). The …

A bstract Axion-like particles (ALPs) are ubiquitous in models of new physics explaining
some of the most pressing puzzles of the Standard Model. However, until relatively recently …

Generative networks are a class of machine learning algorithms designed to generate
samples according to a multidimensional function, given a randomly distributed input …

The tau neutrino is probably the least studied particle in the standard model (SM), with only
a handful of interaction events being identified so far. This can in part be attributed to their …

Proton beam-dump experiments are a high-intensity source of secondary muons and
provide an opportunity to probe muon-specific dark sectors. We adopt a simplified-models …

Many existing or proposed intensity-frontier search experiments look for decay signatures of
light long-lived particles (LLPs), highly displaced from the interaction point, in a distant …
