Improved reconstruction of highly boosted $\tau$-lepton pairs in the $\tau\tau\rightarrow(\mu\nu_{\mu}\nu_{\tau})({hadrons}+\nu_{\tau})$ decay channels with the ATLAS detector / ATLAS Collaboration
This paper presents a new $\tau$-lepton reconstruction and identification procedure at the ATLAS detector at the Large Hadron Collider, which leads to significantly improved performance in the case of physics processes where a highly boosted pair of $\tau$-leptons is produced and one $\tau$-lepton decays into a muon and two neutrinos ($\tau_{\mu}$), and the other decays into hadrons and one neutrino ($\tau_{had}$).

A study of local multiplicity fluctuations in charged particle production in Xe-Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV using ALICE / Banoo, Zarina (Jammu U.) ; Gupta, Ramni (Jammu U.) /ALICE Collaboration
A fundamental characteristic of the critical behaviour of a system undergoing phase transition is that it exhibits fluctuations of all scales. The most efficient way to address fluctuations of a system created in a heavy-ion collision is to investigate event-by-event (E-by-E) fluctuations, where a given observable is measured on an event-by-event basis, and the fluctuations are studied over the ensemble of the events.

Test of lepton flavour universality in $W$-boson decays into electrons and $\tau$-leptons using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the ratio of the branching fractions, $R_{\tau/e} = B(W \to \tau \nu)/ B(W \to e \nu)$, is performed using a sample of $W$ bosons originating from top-quark decays to final states containing $\tau$-leptons or electrons. [...]
