 Exclusive dimuon production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV with ATLAS Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, $\mathrm{PbPb} (\gamma\gamma) \rightarrow \mu\mu (\mathrm{Pb}^{(\star)}\mathrm{Pb}^{(\star)} )$, is studied using $\mathcal{L}_{\mathrm{int}} = 0.48$ nb$^{-1}$ of $\sqrt{s_\mathrm{NN}}=5.02$ TeV lead-lead collision data at the LHC with the ATLAS detector.

 Latest results on light (anti)nuclei production in Pb-Pb collisions with ALICE at the LHC / Pinto, Chiara Recent results on the production of light nuclei, including deuterons, tritons, $^3$He, $^4$He and the corresponding antinuclei in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV are presented and compared with theoretical predictions to provide insight into their production mechanisms in heavy-ion collisions.

 Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W, \, Z$, or Higgs boson.

 Tetra-quarks, penta-quarks and the like: old and new views / Rossi, Giancarlo ; Veneziano, Gabriele In this talk, after a short overview of the history of the discovery of tetra-quarks and penta-quarks, we will discuss a possible interpretation of such states in the framework of a 40-years-old "string junction" picture that allows a unified QCD description of ordinary mesons and baryons as well as multi-quark resonances.. arXiv:2011.09774 ; CERN-TH-2020-197. - Fulltext
