“…In heavy-ion collisions, the long-range correlations are known to arise from the collective dynamics of the produced quark-gluon plasma (QGP). The similarity between the $pp$ and heavy-ion measurements raises the possibility that a tiny droplet of the QGP is produced even in $pp$ collisions. …”

“…This thesis presents a search for resonant production of highly energetic Higgs boson pairs, with each Higgs boson decaying to a $b$-quark pair, with the ATLAS detector. This analysis uses the complete ATLAS run 2 dataset of 139.0 $\text{fb}^{-1}$ of proton-proton collisions at a centre-of-mass energy of $\sqrt{s}= 13$ TeV. …”

“…The physics of heavy ions is not limited to the study of the hot matter created when they collide (QGP, Quark-Gluon Plasma); the nuclear environment modifies the behaviour of their constituents independently on the subsequent QGP formation. …”

“…In particular, charm mesons are of vivid interest in the context of the phase-transition between confined hadronic matter and the quark-gluon plasma. Recently, the experimental setup of NA61/SHINE experiment was supplemented with a small-acceptance version of the Vertex Detector (SAVD) which was motivated by the importance and the possibility of the first direct measurements of open charm mesons in heavy ion collisions at SPS energies. …”

“…In addition, the impact of existing measurements of jet and W boson production and at the center-of-mass energy of 8 TeV, as well as the top quark pair production at the center-of-mass energy of 5.02 TeV at the LHC on PDFs are quantified via including them in a QCD analysis.…”

“…The observation is consistent with the background-only hypothesis, and limits are set on the product of the cross-section of top squark pair production and the branching fraction to a lepton and a $b$ or $d$ quark through an R-parity-violating vertex. For a proper decay length hypothesis of 2 cm,top squarks with masses up 1500 GeV are excluded at the 95 % confidence level.…”

The events simulated with the $bb4\ell$ generator are interfaced with Pythia 8 for the simulation of the Parton Shower (PS) and hadronisation and compared to different $tW$ generator setups. …”

“…The availability of high-intensity kaon beams at the J-PARC Hadron Experimental Facility and the CERN SPS North Area, together with the abundant forward production of kaons at the LHC, gives rise to unique possibilities for sensitive tests of the Standard Model in the quark flavor sector. Precise measurements of the branching ratios for the flavor-changing neutral current decays $K\to\pi\nu\bar{\nu}$ can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. …”

“…Among them there is a twin-ring e⁻e⁺ collider capable to run at beam energies between 45.6 and 182.5 GeV, i.e. the energies corresponding to the resonances of the Z, W, H bosons and the top quark. The conceptual design of the two 100-km rings has advanced to what is believed to be a working solution, i.e. capability to deal with low-energy (45.6 GeV) high-current (1390 mA) version as well as the high-energy (182.5 GeV) low-current (5.4 mA) one, with intermediate energy and current steps for the other 2 resonances. …”
