Observation of the rare baryonic decay $B^{+} \rightarrow p \bar{\Lambda}$ and measurement of its weak decay parameter
The first observation of the decay $B^{+} \rightarrow p \bar{\Lambda}$ is presented, using proton-proton collision data collected by the LHCb experiment between 2016 and 2018 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $5.4fb{-1}$. [...]

Measurement of the top-quark mass using decays with a $J/\psi$ meson at $\sqrt{s}=$13 TeV with the ATLAS detector
The top-quark mass is measured using top-quark decays producing an isolated lepton and $J/\psi$ meson reconstructed in its $\mu^+\mu^-$ decay mode. [...]

Worldsheet for Generalized Veneziano Amplitudes / Komatsu, Shota (CERN) ; Maity, Pronobesh (Ecole Polytechnique, Lausanne)
We present a worldsheet action that reproduces a class of dual resonance amplitudes discussed in the literature, which generalize the Veneziano amplitude for open strings. [...]

Sample-based training of quantum generative models / Demidik, Maria (DESY, Zeuthen ; Cyprus Inst.) ; Tüysüz, Cenk (CERN) ; Grossi, Michele (CERN) ; Jansen, Karl (DESY, Zeuthen ; Cyprus Inst.)
Quantum computers can efficiently sample from probability distributions that are believed to be classically intractable, providing a foundation for quantum generative modeling. [...]

Euclid: From Galaxies to Gravitational Waves – Forecasting Stochastic Gravitational Wave Background Anisotropies and Their Cross-Correlation / Euclid Collaboration
We estimate the amplitude and spatial anisotropy in the stochastic gravitational wave background (SGWB) energy density due to compact binary coalescence (CBC) events: binary black holes (BBH), binary neutron stars (BNS), and black hole-neutron star (BHNS) mergers. [...]

Search for $H\rightarrow c\bar{c}$ and measurement of $H \rightarrow b\bar{b}$ in vector-boson fusion production with the ATLAS detector
A search for Standard Model (SM) Higgs bosons produced via vector-boson fusion at the Large Hadron Collider and decaying into a charm quark-antiquark pair ($H \rightarrow c\bar{c}$) is presented. [...]

Florence (main) ; INFN, Florence) et al.
A QKD link established between Sicily (Italy) and Malta has been utilized to test the performances of a fast-gated InGaAs single photon detector, achieving a fourteen times higher key rate than using a commercial detector..
