“…The word “confinement” in the context of hadronic physics originally referred to the fact that quarks and gluons appear to be trapped inside mesons and baryons, from which they cannot escape. …”

“…Higher order effects are very relevant for ttW production. In the absence of gluon-induced channels at LO, the latter only appear at higher orders and give sizeable contributions to the cross section. …”

“…Theoretical predictions suggest that such modulations may provide new insight into nuclear structure and may shed light on the transverse momentum dependent (TMD) distributions of gluons within large nuclei - a topic of great interest both at existing experiments and at a future Electron Ion Collider…”

“…A Randall-Sundrum graviton G, with a mass smaller than 0.8 TeV (0.8 TeV) can be excluded if using m_{\ell\ellbb} (m^{NW}_{tt̄}). A Kaluza-Klein gluon g_{KK} , with a mass smaller than 3.1 TeV (3.25 TeV) can be excluded if using m_{\ell\ellbb} (m^{NW}_{tt̄}).…”

“…Fixed-order predictions cannot describe the vector boson production process in low transverse momentum regions where resummation of soft gluon emission is essential. Using a ResBos Monte Carlo package, we perform the resummed theoretical predictions for the transverse momentum distributions of Z boson measured in proton-proton collision at $\sqrt{s}=8$TeV with ATLAS detector at LHC. …”

“…--HTML--><p><span><span>In the ultra-relativistic heavy-ion collisions at the Large Hadron Collider (LHC), a state of matter, called quark-gluon plasma (QGP), is created. Measurements of the production of charm hadrons and leptons from c,b-hadron decays in nucleus--nucleus collisions are therefore useful to study the properties of the in-medium charm-quark energy loss via the comparison with theoretical calculations.…”

“…Upper limits at $95\%$ confidence level (CL) are set on the products of the branching fraction for the decay into $\tau$ leptons and the cross sections for the production of a resonance $\phi$ in addition to the observed Higgs boson via gluon fusion ($\mathrm{gg}\phi$) or in association with b quarks, ranging from $\mathcal{O}(10~\mathrm{pb})$ (at $60~\mathrm{GeV}$) to 0.3 fb (at $3.5~\mathrm{TeV}$) each. …”

“…These observations are consistent with previous measurements that used two-particle correlations, and with an interpretation in terms of parton energy loss in a high-density quark gluon plasma. These yield modifications vanish in peripheral Pb$-$Pb collisions and are not observed in either high-multiplicity pp or p$-$Pb collisions.…”

“…The algorithm runs on the PUPPI particles in each jet, and is capable of discriminating between jets originating from bottom quarks and jets originating from light quarks or gluons. The expected performance and physics implication of this algorithm is shown using Monte Carlo samples with 200 pileup interactions, simulating the conditions of the HL-LHC.…”

“…A Large Ion Collider Experiment (ALICE), situated on the Large Hadron Collider (LHC), is optimised to study relativistic heavy-ion collisions in order to quantitatively characterise the Quark Gluon Plasma. The inner-most detector system, the Inner Tracking System (ITS), is responsible for primary and secondary vertex reconstruction in the vicinity of the interaction point, as well as stand-alone tracking of particles unable to reach the rest of the ALICE sub-detectors, due to momentum cut-off and acceptance limitations. …”

“…Event-by-event fluctuations of conserved quantities such as electric charge, baryon number, and strangeness in ultrarelativistic heavy-ion collisions provide insight into the properties of the quark-gluon plasma and the QCD phase diagram. The net-charge fluctuations in finite phase space are usually studied using the $\nu_{dyn}[+,-]$ observable, which is robust against the detection efficiency losses. …”
