“…[630], if the mass of the ALP is in the range 3-10 GeV/c 2 , LHCb has the world-best sensitivity to discover such a particle. The main reason for this is the special trigger configuration at LHCb [988], which provides high efficiency to reconstruct relatively soft photon pairs.…”

Feebly-interacting particles: FIPs 2020 workshop report

et al. 2021

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 particle and astrophysics community for exploring the physics of light and feebly-interacting particles as a paradigm complementary to a New Physics sector at the TeV scale and beyond. FIPs 2020 has been the first workshop fully dedicated to the physics of feebly-interacting particles and was held virtually from 31 August to 4 September 2020. The workshop has gathered together experts from collider, beam dump, fixed target experiments, as well as from astrophysics, axions/ALPs searches, current/future neutrino experiments, and dark matter direct detection communities to discuss progress in experimental searches and underlying theory models for FIPs physics, and to enhance the cross-fertilisation across different fields. FIPs 2020 has been complemented by the topical workshop “Physics Beyond Colliders meets theory”, held at CERN from 7 June to 9 June 2020. This document presents the summary of the talks presented at the workshops and the outcome of the subsequent discussions held immediately after. It aims to provide a clear picture of this blooming field and proposes a few recommendations for the next round of experimental results.

“…Moreover, during 2018 data taking, a trigger to select both converted and unconverted diphotons based on a neural network was introduced. This is a novel technique which was never used before for this kind of multi-body decays at LHCb [70]. A similar trigger strategy could be adopted in run 3 by introducing selection features to account for different conditions such as higher multiplicity and pile-up.…”

Unleashing the full power of LHCb to probe stealth new physics

et al. 2022

In this paper, we describe the potential of the LHCb experiment to detect Stealth physics. This refers to dynamics beyond the Standard Model that would elude searches that focus on energetic objects or precision measurements of known processes. Stealth signatures include long-lived particles and light resonances that are produced very rarely or together with overwhelming backgrounds. We will discuss why LHCb is equipped to discover this kind of physics at the Large Hadron Collider and provide examples of well-motivated theoretical models that can be probed with great detail at the experiment.

The main reason for this is the special trigger configuration at LHCb [978], which provides high efficiency to reconstruct relatively soft photon pairs. The final case I will cover is the potential discovery of Dark Matter (DM) at LHCb.…”
