Observation of a $B_c^{*+}$ meson with the ATLAS detector / ATLAS Collaboration
The first observation of a new meson state decaying into $B_c^+$ and a photon is presented using a dataset of $pp$ collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb$^{-1}$ [...]

Search for charginos and neutralinos with $B-L$ $R$-parity violating decays in $\sqrt{s}=13$ TeV and $13.6$ 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. [...]

Exclusive dimuon production and coherent charmonium photoproduction at forward rapidity in ultra-peripheral Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.36$ TeV / Ali Hassan Abdallah, Dana (Wayne State U.) ; Abualrob, Ibrahim Jaser (Houston U.) ; Acharya, Shreyasi (INFN, Bari) ; Agarwal, Kshitij (Trieste U. ; INFN, Trieste) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahuja, Ishaan (Kosice U.) et al. /ALICE
This Paper presents rapidity-differential measurements of coherent J/$\psi$ and $\psi({\rm 2S})$ photoproduction, as well as rapidity- and mass-differential measurements of exclusive dimuon production, in the forward rapidity region $-4 < y < -2.5$ in ultra-peripheral Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.36$ TeV using data recorded by the ALICE detector at the LHC in 2023, corresponding to an integrated luminosity of $\mathcal{L} = 1170 \pm 50~\mu{\rm b}^{-1}$. The J/$\psi$ and $\psi({\rm 2S})$ results reveal the significant role of nuclear shadowing effects. [...]

Study of Particle Fluence Effects on Collected Charge and Depletion Voltage of the ATLAS IBL Planar Pixel Sensors / ATLAS Collaboration
After ten years of operation at the LHC, the planar pixel sensors of the innermost barrel layer of the ATLAS Pixel detector have accumulated an average bulk damage fluence in excess of $2\times10^{15}$ 1 MeV-neutrons equivalent/cm$^2$. [...]

Search for light charged Higgs bosons decaying to charm and strange quarks in $ \mathrm{t} \overline{\mathrm{t}} $ events in proton-proton collisions at $ \sqrt{s}= $ 13 TeV / CMS Collaboration
A search is presented for a light charged Higgs boson $ \mathrm{{H}^{\pm}} $ in top quark pair production ( $ \mathrm{t} \overline{\mathrm{t}} $), where one of the top quarks decays to an $ \mathrm{{H}^{\pm}} $ and a bottom quark, while the other decays to a $ \mathrm{W}^{\mp} $ boson and a bottom quark [...]

Study of $t\bar{t}$ threshold effects in $e\mu$ differential distributions measured in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration
The recent ATLAS measurement of the normalised $e\mu$ dilepton invariant mass and azimuthal angle distributions in $\sqrt{s}=13$ TeV $pp$ collisions at the Large Hadron Collider is extended to study the sensitivity to the formation of quasi-bound states near the $t\bar{t}$ threshold. [...]

Measurement of jet photoproduction in ultra-peripheral Pb+Pb collisions without nuclear breakup at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV with the ATLAS detector / ATLAS Collaboration
In ultra-relativistic heavy ion collisions at the LHC, each nucleus acts as a source of high-energy quasi-real photons that can participate in scattering processes without causing either participating nucleus to break up and emit forward neutrons. [...]
