Search for vector-like quark, heavy neutral lepton and long-lived particles at ATLAS and CMS / Grancagnolo, Sergio (INFN Lecce e Universita del Salento (IT))
Various theories beyond the Standard Model predict heavy neutral leptons, or long-lived particles with unique signatures which are difficult to reconstruct. [...]

Reinterpretation of electroweak supersymmetry searches with final states containing taus in models of variable $R$-parity-violating coupling strength
Two ATLAS searches for supersymmetric particles in final states with multiple leptons, optimized for $R$-parity-conserving and $R$-parity-violating models, are reinterpreted in models with variable $R$-parity-violating couplings. [...]

Measurement of the W and Z boson cross section at $\sqrt{s} =$ 13.6 TeV with the ATLAS detector / Marinescu, Mihaela (University of Birmingham (GB))
This article reports the measurement of the ${W^\pm}$ and ${Z}$ boson cross sections, their ratios and the ratio of the $t\bar{t}$ and \ensuremath{W} boson fiducial cross sections, using proton-proton collision data obtained at the new centre-of-mass energy of $\sqrt{s} = $ 13.6 TeV by the ATLAS experiment at the Large Hadron Collider.

Searches for new phenomena in final states with taus using the ATLAS detector / Carratta, Giuseppe (Universita e INFN, Bologna (IT))
Many theories beyond the Standard Model predict new phenomena, such as leptoquarks, vector like leptons, $Z'$ and $W'$ bosons, supersymmetry, new scalars or heavy leptons, in final states with isolated, high-$p_T$ taus. [...]
