“…Ar+Sc may be the smallest of studied systems, in which colliding nu- cleons create not a number of isolated N+N events, but a collectively evolving fireball, with a possible formation of quark-gluon plasma at top SPS energies. Methodology Collisions of Ar+Sc were recorded in 2015 by the NA61/SHINE Collabora- tion. …”

“…Even though ALICE was designed for the study and characterization of the quark gluon plasma, which is generated at heavy nuclei accelerators (like LHC), ALICE also takes data during pp collisions in LHC, the data taken during this period serves like a reference or the heavy ion phase, but also is used to perform analysis where ALICE is competitive with other LHC experiments. …”

“…A Large Ion Collider Experiment(ALICE) at the Large Hadron Collider(LHC) at CERN will undergo a major upgrade during the 2nd LHC Long Shutdown(LS2) scheduled in 2019~2021 that will allow to study in detail of strong interaction matter Quark-Gluon Plasma(QGP) properties. To collecting more Pb-Pb events during the Run 3 and Run 4, the replacement of the existing Inner Tracking System(ITS) with a completely new ultra-light high resolution detector based on Monolithic Active Pixel Sensors(MAPS) technique is one of the cornerstones within this upgrade program. …”

“…A golden channel for measuring vector boson scattering at the collider is the electroweak production of two $W$ bosons with the same electric charges. Owing to its largest quark- to gluon- induced production ratio among other diboson combinations, the process was also the first target of the ATLAS vector boson scattering program, with evidence made in 2014 and observation in 2019. …”
