Investigating baryon-strangeness and charge-strangeness correlations in Pb$-$Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV with ALICE / Saha, Swati (NISER, Jatni ; HBNI, Mumbai)
To explore the quantum chromodynamics (QCD) phase transitions and the properties of quark$-$gluon plasma, the ALICE collaboration at CERN has conducted an extensive analysis of the correlations among net-conserved quantities, namely net-baryon, net-charge, and net-strangeness. [...]

Measurement of top-quark pair production in association with charm quarks in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
Inclusive cross-sections for top-quark pair production in association with charm quarks are measured with proton-proton collision data at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 140 fb$^{-1}$, collected with the ATLAS experiment at the LHC between 2015 and 2018.

Measurement of photonuclear jet production in ultra-peripheral Pb+Pb collisions at $\sqrt{s_{\text{NN}}} = 5.02$ TeV with the ATLAS detector / ATLAS Collaboration
In ultra-relativistic heavy ion collisions, the photoproduction of high-energy jets can be used to constrain nuclear parton distributions for a wide range of parton kinematics. [...]

Search for light long-lived particles decaying to displaced jets in proton-proton collisions at $ \sqrt{s} = $ 13.6 TeV / CMS Collaboration
A search for light long-lived particles decaying to displaced jets is presented, using a data sample of proton-proton collisions at a center-of-mass energy of 13.6 TeV, corresponding to an integrated luminosity of 34.7 fb$ ^{-1} $, collected with the CMS detector at the CERN LHC in 2022. [...]
