Observation of $VVZ$ production at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for the production of three massive vector bosons, $VVZ (V=W, Z)$, in proton-proton collisions at $\sqrt{s} = 13$ TeV is performed using data with an integrated luminosity of $140$ fb$^{-1}$ recorded by the ATLAS detector at the Large Hadron Collider. [...]

Expected Tracking Performance of the ATLAS Inner Tracker at the High-Luminosity LHC / ATLAS Collaboration
The high-luminosity phase of LHC operations (HL-LHC), will feature a large increase in simultaneous proton-proton interactions per bunch crossing up to 200, compared with a typical leveling target of 64 in Run 3. [...]

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 ($\tau_{had}$).

Search for Higgs boson decays into a pair of pseudoscalar particles in the $\gamma\gamma\tau_{\text{had}}\tau_{\text{had}}$ final state using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for exotic decays of the 125 GeV Higgs boson into a pair of new spin-0 particles, $H \to aa$, where one decays into a photon pair and the other into a $\tau$-lepton pair, is presented. [...]

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. [...]

Cross-section measurements for the production of a $W$-boson in association with high-transverse-momentum jets in $pp$ collisions at $\sqrt{s}$= 13 TeV with the ATLAS detector / ATLAS Collaboration
A set of measurements for the production of a $W$-boson in association with high-transverse-momentum jets is presented using 140 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of $\sqrt{s}=13$ TeV collected by the ATLAS detector at the LHC. [...]

Event-by-event local multiplicity fluctuations in charged particle production at the LHC energies with ALICE / Malik, Salman Khurshid (Jammu U.) ; Sharma, Sheetal (Jammu U.) ; Gupta, Ramni (Jammu U.) /ALICE Collaboration
The plasma of strongly interacting quarks and gluons (QGP) is formed in ultrarelativistic heavy-ion collisions. Charged particle multiplicity fluctuations are one of the key observables for studying the properties of the QGP formed in such collisions, in particular the phase transition from QGP to hadron gas.

Neural simulation-based inference is a powerful class of machine-learning-based methods for statistical inference that naturally handles high-dimensional parameter estimation without the need to bin data into low-dimensional summary histograms. [...]
