“…The efficiencies global muon , p T , isolation correspond to the fractions of particles passing the global muon, p T and R≤0.3 p T requirements, respectively, out of the particles passing all selections imposed prior to them (online selection included). The aforementioned values were given in [23] for lepton-like particles of charges 1-8 and masses of 100-1000 GeV. Since they vary weakly with mass, we use m = 1000 GeV efficiencies for all m ≥ 1000 GeV particles.…”

“…In addition, triggering particles must be fast enough to have both their ID and muon system (MS) tracks in the same bunch crossing [22]. Since the LHC collisions were planned to occur every 25 ns, slow particles that reach the MS more than 25 ns after a β = 1 particle, will be associated with the wrong bunch crossing and thus will not have a matching ID track [23]. An additional resistive plate chamber (RPC) muon trigger was applied for η ≤ 1.6, allowing candidates to reach the MS up to 50 ns later than a β = 1 particle [24].…”

Colored and colorless particles that are stable on collider scales and carry exotic electric charges, so-called multiply-charged heavy stable particles (MCHSPs), exist in extensions of the Standard Model, and can include the top partner(s) in solutions of the hierarchy problem. To obtain bounds on color-triplets and color-singlets of charges up to |Q| = 8, we recast searches for signatures of two production channels: the "open" channel -where the particles are pair-produced above threshold, and are detectable in dedicated LHC searches for stable multiply charged leptons, and the "closed" channel -where a particle-antiparticle pair is produced as a bound state, detectable in searches for a diphoton resonance. We recast the open lepton searches by incorporating the relevant strong-interaction effects for color-triplets. In both open and closed production, we provide a careful assessment of photon-induced processes using the accurate LUXqed PDF, resulting in substantially weaker bounds than previously claimed in the literature for the colorless case. Our bounds for colored MCHSPs are shown for the first time, as the LHC experiments have not searched for them directly. Generally, we obtain nearly charge-independent lower mass limits of around 970 GeV (color-triplet scalar), 1200 GeV (color-triplet fermion), and 880 − 900 GeV (color-singlet fermion) from open production, and strongly chargedependent limits from closed production. In all cases there is a cross-over between dominance by open and closed searches at some charge. We provide prospective bounds for √ s = 13 TeV LHC searches at integrated luminosities of 39.5 fb −1 , 100 fb −1 , and 300 fb −1 . Moreover, we show that a joint observation in the open and the closed channels allows to determine the mass, spin, color, and electric charge of the particle.

Discovery prospects for long-lived multiply charged particles at the LHC

et al. 2022

In this work, we aim to provide a comprehensive and largely model independent investigation on prospects to detect long-lived multiply charged particles at the LHC. We consider particles with spin 0 and $$\frac{1}{2}$$ 1 2 , with electric charges in range $$1 \le |Q/e| \le 8$$ 1 ≤ | Q / e | ≤ 8 , which are singlet or triplet under $$SU(3)_C$$ S U ( 3 ) C . Such particles might be produced as particle-antiparticle pairs and propagate through detectors, or form a positronium (quarkonium)-like bound state. We consider both possibilities and estimate lower mass bounds on new particles, that can be provided by ATLAS, CMS and MoEDAL experiments at the end of Run 3 and HL-LHC data taking periods. We find out that the sensitivities of ATLAS and CMS are generally stronger than those of MoEDAL at Run 3, while they may be competitive at HL-LHC for $$3 \lesssim |Q/e| \lesssim 7$$ 3 ≲ | Q / e | ≲ 7 for all types of long-lived particles we consider.
