Search for Z' bosons decaying into charginos in final states with two oppositely charged leptons and missing transverse momentum in pp collisions at $\sqrt{s}$ = 13 TeV
Massive leptophobic Z' bosons decaying to a pair of charginos are searched for in proton-proton collisions at $\sqrt{s}$ = 13 TeV, using data samples collected by the CMS experiment in 2016, 2017, and 2018, corresponding to a total integrated luminosity of 138 fb$^{-1}$. [...]

Renormalisation and matching of massless scalar correlation functions in Soft de Sitter Effective Theory / Beneke, Martin (Munich, Tech. U.) ; Hager, Patrick (CERN) ; Sanfilippo, Andrea F. (Granada U.)
For light and massless scalar fields, cosmological correlation functions suffer from infrared divergences and secular logarithms. [...]

First measurement of the decay-time-integrated $C\!P$ asymmetry in $B_s^0 \to D_s^- \pi^+$ decays
A measurement of the flavour-untagged decay-time-integrated ${C\!P}$ asymmetry in the flavour-specific decay ${B_s^0 \to D_s^-\pi^+}$, ${\langle A^s_{\rm untagged}\rangle}$, is performed using proton-proton collision data collected by the LHCb experiment between 2016 and 2018 at a center-of-mass energy of ${13\,{\rm TeV}}$, corresponding to a total integrated luminosity of ${5.4\,{\rm fb}^{-1}}$.

New axion bounds derived from the 100-parsec Gaia DR3 white dwarf luminosity function / Alberino, Martín L (Unlisted, AR ; UNLP, La Plata (main)) ; Miller Bertolami, Marcelo M (Unlisted, AR ; UNLP, La Plata (main)) ; Camisassa, María E (Barcelona, Polytechnic U.) ; Caputo, Andrea (CERN ; Rome U. ; INFN, Rome ; Weizmann Inst.) ; Torres, Santiago (Barcelona, Polytechnic U.)
The axion, a well-motivated hypothetical particle arising in extensions of the Standard Model, can be produced copiously within the hot, compact cores of white dwarf stars. [...]

Universality of the Blandford-Znajek emission in stationary and axisymmetric spacetimes / Camilloni, Filippo (Goethe U., Frankfurt (main)) ; Rezzolla, Luciano (Goethe U., Frankfurt (main) ; CERN ; Trinity Coll., Dublin)
The Blandford-Znajek (BZ) mechanism is widely recognised as the most compelling process to extract rotational energy from an accreting black hole and power the emission of relativistic jets. [...]
