Abstract Motivated by the expectation that new physics may manifest itself in the form of very heavy new particles, most of the operation time of the Large Hadron Collider (LHC) is devoted to proton-proton (pp) collisions at the highest achievable energies and collision rates. The large collision rates imply tight trigger requirements that include high thresholds on the final-state particles’ transverse momenta pT and an intrinsic background in the form of particle pileup produced by different… 



Searching for New Long-Lived Particles in Heavy-Ion Collisions at the LHC.

It is shown that the looser triggers alone can make searches in heavy-ion data competitive with proton data for the specific example of heavy neutrinos in the neutrino minimal standard model, produced in the decay of B mesons.

New long-lived particle searches in heavy-ion collisions at the LHC

We show that heavy ion collisions at the LHC provide a promising environment to search for signatures with displaced vertices in well-motivated New Physics scenarios. Compared to proton collisions,

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider

Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC)

New physics searches with heavy-ion collisions at the CERN Large Hadron Collider

This document summarises proposed searches for new physics accessible in the heavy-ion mode at the CERN Large Hadron Collider (LHC), both through hadronic and ultraperipheral $\gamma\gamma$

Opportunities for new physics searches with heavy ions at colliders

Opportunities for searches for phenomena beyond the Standard Model (BSM) using heavyions beams at high energies are outlined. Different BSM searches proposed in the last years in collisions of heavy

Soft displaced leptons at the LHC

Soft displaced leptons are representative collider signatures of compressed dark sectors with feeble couplings to the standard model. Prime targets are dark matter scenarios where co-scattering or

Searching for Axionlike Particles with Ultraperipheral Heavy-Ion Collisions.

It is shown that ultraperipheral heavy-ion collisions at the Large Hadron Collider can be used to search for axionlike particles with mass below 100 GeV, and new and updated limits from recasting multiphoton searches at LEP II and the LHC are presented.

Feebly-interacting particles: FIPs 2020 workshop report

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

Tuning PYTHIA 8.1: the Monash 2013 tune

We present an updated set of parameters for the PYTHIA 8 event generator. We reevaluate the constraints imposed by LEP and SLD on hadronization, in particular with regard to heavy-quark fragmentation
