In this work we analyze the reliability of several techniques for computing jet and hadron spectra at different collision energies. This is of particular relevance for discovering energy loss in the upcoming oxygen-oxygen (OO) run at the LHC, for which a reference $pp$ run at the same energy is currently not planned. For hadrons and jets we compute the ratio of spectra between different $pp$ collision energies in perturbative QCD, which can be used to construct a $pp$ reference spectrum. Alternatively, a $pp$ reference can be interpolated from measured spectra at nearby energies. We estimate the precision and accuracy of both strategies for the spectra ratio relevant to the oxygen run, and conclude that the central values agree to 4% accuracy for hadrons and 2% accuracy for jets. As an alternative, we propose taking the ratio of OO and $pp$ spectra at different collision energies, which cleanly separates the experimental measurement from the theoretical computation.
It has been observed that the yields of strange and multi-strange hadrons relative to pion increase significantly with the event charged-particle multiplicity. We notice from experimental data that yield ratios between non-strange hadrons, like p/$pi
Phenomenological Tsallis fits to the CMS and ATLAS transverse spectra of charged particles were found to extend for p_T from 0.5 to 181 GeV in pp collisions at LHC at sqrt{s}=7 TeV, and for p_T from 0.5 to 31 GeV at sqrt{s}=0.9 TeV. The simplicity of
Recent experiments have observed large anisotropic collective flows in high multiplicity proton-lead collisions at the Large Hadron Collider (LHC), which indicates the possible formation of mini quark-gluon plasma (QGP) in small collision systems. Ho
In this article, we will present a systematic analysis of transverse momentum spectra of the strange hadron in different multiplicity events produced in pp collision at $sqrt{s}$ = 7 TeV, pPb collision at $sqrt{s_{NN}}$ = 5.02 TeV and PbPb collision
We have performed a systematic study of $J/psi$ and $psi(2S)$ production in $p-p$ collisions at different LHC energies and at different rapidities using the leading order (LO) non-relativistic QCD (NRQCD) model of heavy quarkonium production. We have
