“…ALICE is one of the four main experiments at the Large Hadron Collider (LHC), mainly focused on heavy-ion collisions in which the Quark-Gluon Plasma (QGP) could be produced. One of the tools to study the properties of the QGP and the process of hadron production are two-particle angular correlations. …”

“…The analysis uses event categories targeting Higgs boson production via gluon-fusion and vector boson fusion. An upper limit on the Higgs boson branching fraction to an electron pair is determined as $3.0\times10^{-4}$ ($3.0\times10^{-4}$ expected) at the $95\%$ confidence level. …”

“…The enhanced production of strangeness was first proposed as a signature of the quark gluon plasma creation in heavy ion collisions. Recently, increased strangeness production is also observed experimentally in high multiplicity small systems such as pp and pPb collisions, where formation of QGP is not expected. …”

“…Model differences observed for jets initiated by quarks or gluons produced in the hard scattering process are dominated by the differences in these hadron energy fractions indicating that measurements of the hadron content of jets and improved tuning of hadronization models can result in an improvement in the precision of the knowledge of the ATLAS jet energy scale.…”

“…Since charm and beauty quarks are predominantly produced in the hard scattering process of colliding nuclei, they serve as unique probes to study the quark-gluon plasma in Pb-Pb collisions. In addition, recent investigations of hadronisation mechanisms have revealed interesting and unexpected features when comparing measurements in $e^+e^-$ and in hadronic collisions as in pp, p-Pb and Pb-Pb. …”
