Abstract.The cross section for anti-deuteron photoproduction is measured at HERA at a mean centre-of-mass energy of $W_{\gamma p} = 200$ GeV in the range 0.2 < pT/M < 0.7 and |y| < 0.4, where M, pT and y are the mass, transverse momentum and rapidity of the anti-deuteron in the HERA laboratory frame, respectively. The numbers of anti-deuterons per event are found to be similar in photoproduction to those in central proton-proton collisions at the CERN ISR but much lower than those in central Au… 
Production of light nuclei and anti-nuclei in pp and Pb-Pb collisions at LHC energies
The production of (anti-)deuteron and (anti-)3He nuclei in Pb–Pb collisions at √ sNN = 2.76 TeV has been studied using the ALICE detector at the LHC. The spectra exhibit a significant hardening with
Searches for heavy long-lived charged particles with the ATLAS detector in proton-proton collisions at s=8$$ \sqrt{s}=8 $$ TeV
A bstractSearches for heavy long-lived charged particles are performed using a data sample of 19.1 fb−1 from proton-proton collisions at a centre-of-mass energy of s=8$$ \sqrt{s}=8 $$ TeV collected
Optimization of muon timing and searches for heavy long-lived charged particles with the Compact Muon Solenoid detector at the Large Hadron Collider
Proton-proton collisions at the Large Hadron Collider at sqrt(s) = 7 and 8 TeVare studied using the Compact Muon Solenoid (CMS) detector. The measurement and improvements to the arrival time of
University of Groningen Search for long-lived heavy charged particles using a ring imaging Cherenkov technique at LHCb Aaij,
A search is performed for heavy long-lived charged particles using 3.0 fb−1 of proton–proton collisions collected at √ s = 7 and 8 TeV with the LHCb detector. The search is mainly based on the
Search for out-of-time decays of stopped particles at the ATLAS detector
On July 4 2012, the ATLAS and CMS experiments announced the discovery of a new particle, later declared to be one of possibly many Higgs bosons [51, 53]. The Higgs mechanism has been so successful
