Branching fraction measurement of the decay $B^+ \to \psi(2S) \phi(1020) K^+$ / LHCb Collaboration
The branching fraction of the decay $B^+\to \psi(2S)\phi(1020)K^+$, relative to the topologically similar decay $B^+\to J/\psi \phi(1020) K^+$, is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of $9\,\mathrm{fb}^{-1}$.

Curvature Perturbations from First-Order Phase Transitions: Implications to Black Holes and Gravitational Waves / Franciolini, Gabriele (CERN) ; Gouttenoire, Yann (Tel Aviv U. ; U. Mainz, PRISMA ; Mainz U., Inst. Phys.) ; Jinno, Ryusuke (Kobe U.)
We employ a covariant formalism to study the evolution of cosmological perturbations during a first-order phase transition, addressing in particular their gauge dependence that have been overlooked so far. [...]

Di-decay signature of new physics particles at intensity frontier experiments / Dalla Valle Garcia, Giovani (KIT, Karlsruhe, IAP) ; Ovchynnikov, Maksym (CERN)
We explore the potential of intensity frontier experiments to search for unstable feebly interacting particles (FIPs) via signatures that offer deeper insights than the standard signature of a single FIP decay. [...]

Luminosity measurement for lead-lead collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}}= $ 5.02 TeV in 2015 and 2018 at CMS
Measurements of the luminosity delivered to the CMS experiment during the lead-lead data-taking periods in 2015 and 2018 are presented for the first time. [...]

Measurement of double-differential charged-current Drell-Yan cross-sections at high transverse masses in $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector
This paper presents a first measurement of the cross-section for the charged-current Drell-Yan process $pp\rightarrow W^{\pm} \rightarrow \ell^{\pm} \nu$ above the resonance region, where $\ell$ is an electron or muon [...]
