Ultraperipheral collisions (UPCs) of heavy ions and protons are the energy frontier for
electromagnetic interactions. Both photonuclear and two-photon collisions are studied at …

A new era in the study of high-energy nuclear collisions began when the CERN Large
Hadron Collider (LHC) provided the first collisions of lead nuclei in late 2010. In the first …

This publication describes the methods used to measure the centrality of inelastic Pb-Pb
collisions at a center-of-mass energy of 2.76 TeV per colliding nucleon pair with ALICE. The …

The future opportunities for high-density QCD studies with ion and proton beams at the LHC
are presented. Four major scientific goals are identified: the characterisation of the …

The first measurement of neutron emission in electromagnetic dissociation of Pb 208 nuclei
at the LHC<? format?> is presented. The measurement is performed using the neutron zero …

A good understanding of the luminosity performance in a collider, as well as reliable tools to
analyse, predict, and optimise the performance, is of great importance for the successful …

Abstract The Large Hadron Collider (LHC) at CERN is built to collide intense proton beams
with an unprecedented energy of 7 TeV. The design stored energy per beam of 362 MJ …

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 …

A variety of processes can cause unavoidable beam losses during normal and abnormal
beam operation. Because of the high stored energy of about 700 MJ and the small …

Monte Carlo shower simulations are essential for understanding and predicting the
consequences of beam losses in high-energy proton and ion colliders. Shower simulations …
