Author(s): Davide Pedrotti, Luis A. Escamilla, Valerio Marra, Leandros Perivolaropoulos, and Sunny Vagnozzi The authors demonstrate that, even if fiducial cosmology assumptions cause Baryon Acoustic Oscillation (BAO) measurements to bias low low-redshift acoustic angular scales, this cannot make post-recombination solutions to the Hubble tension plausible. Thus any such biases cannot be potential loopholes to this tension. [Phys. Rev. D 113...

Author(s): Afif Omar and Adam Ritz Despite its strong constraints, the consequences of big bang nucleosynthesis on near-GeV mass dark matter that decays to long-lived light hadrons have received little attention. With minimal model assumptions, the authors establish bounds on the parameter space of mass and branching fractions to hadrons superior to those of other indirect methods. [Phys. Rev.

Author(s): Dogan Akpinar The author computed the gravitational amplitude describing the scattering of a graviton off a massive spinning compact object at the second order expansion in Newton’s constant G (post-Minkowskian expansion), including terms through the quartic order in spin. The spin-induced non-minimal interactions were included in the calculation, thus capturing spin-induced finite-size effects associated with generic compact objects...

Author(s): Jeremy Borden and Yuri V. Kovchegov The proton spin puzzle, how the angular momentum of the proton is composed from its constituents, remains a significant problem for understanding this fundamental quantity in quantum chromodynamics. Previous results suggest that a large contribution to the proton spin comes from partons that carry a very small fraction of the proton’s total momentum. The authors construct an analytic solution to the...

Author(s): Y. Aoki et al. (Flavour Lattice Averaging Group (FLAG) ) The Flavor Lattice Averaging Group has updated their averages of lattice-QCD simulation results of quantities relevant and of interest to high-energy phenomenologists and experimentalists. These include meson decay constants, form factors of semileptonic decays, meson mixing matrix elements, simple nucleon matrix elements, quark masses, and more than half a dozen methods for computing...

Author(s): Sw. Banerjee et al. (Heavy Flavor Averaging Group (HFLAV) ) The Heavy Flavor Averaging Group Collaboration updates their averages of measurements of the properties of hadrons containing a charm or bottom quark and those of the tau lepton, including measurement published in 2023. The averages include neutral meson mixing parameters, CP violation parameters, parameters of semileptonic decays, and Cabibbo-Kobayashi-Maskawa matrix elements...

Author(s): Marina De Amicis, Enrico Cannizzaro, Gregorio Carullo, and Laura Sberna This paper presents an analytical framework for the calculation of quasi-normal modes during the plunge, merger and ringdown phases of compact binary coalescences, which should prove invaluable for shedding light on the complexities of the ringdown phase.
