Hot QCD matter probed via measurements of the speed of sound with CMS / Padula, Sandra (SAO_PAULO) /CMS Collaboration
A hot and dense quark-gluon medium is observed to be created in ultrarelativistic nuclear collisions, exhibiting striking collective flow behavior, with fluid-like properties well described by relativistic hydrodynamics, with minimal viscous dissipation. The characteristics of this medium are under intense investigation, and in particular, its thermodynamical properties. [...]

Reliability assessment of CMS Drift Tubes readout electronics for the HL-LHC upgrade / Toffano, Marco (INFN, Padua)
The new readout electronics of the CMS Drift Tubes detector has been evaluated in terms of its reliability. Starting with a brief overview of the main functionalities of the board, operating requirements and critical elements, an initial estimate of the hardware robustness with respect to expected faults over time is then presented. [...]

Measurements of the Higgs boson production, fiducial and differential cross-sections in the four lepton decay channel using 164 fb$^{-1}$ of data collected at $\sqrt{s}$ = 13.6 TeV with the ATLAS detector
Inclusive, differential and production-mode cross-section measurements of the Higgs boson are performed in the $H \to ZZ^{*} \to 4\ell$ decay channel. [...]

Walking Sudakov: From Cusp to Octagon / Alday, Luis F. (Oxford U., Inst. Math.) ; Armanini, Elisabetta (CERN ; EPFL, Lausanne, FSL) ; Belitsky, Andrei V. (Arizona State U.) ; Häring, Kelian (Delta ITP, Amsterdam) ; Zhiboedov, Alexander (CERN)
We study the Sudakov form factor and the four-point scattering amplitude on the Coulomb branch of planar $\mathcal{N}=4$ SYM as functions of the Coulomb-branch parameters and kinematic invariants. [...]

Bordisms between 9d type IIB supergravities and commutator widths of duality groups / las Heras, Camilo (Valparaiso U.) ; Ruiz, Ignacio (CERN)
We study the topological properties of bordisms interpolating between different 9d gauged supergravities obtained from compactification of type IIB string theory on $\mathbb{S}^1$ with a non-trivial $\mathsf{SL}(2,\mathbb{Z})$ bundle. [...]

Searches for new physics with top quarks in ATLAS and CMS / Iemmi, Fabio (Beijing, Inst. High Energy Phys.) /ATLAS and CMS Collaborations
The latest results by the ATLAS and CMS Collaborations on searches for new physics phenomena involving the production of top quarks are summarized. Both direct searches for new particles and interpretations of Standard Model measurements in terms of the presence of new physics are reported..

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$^{-1}$ [...]
