Twisted Feynman Integrals: from generating functions to spin-resummed post-Minkowskian dynamics / Kim, Joon-Hwi (Caltech) ; Kim, Jung-Wook (CERN ; Potsdam, Max Planck Inst.) ; Lim, Jungwon (Garching, Max Planck Inst.)
We propose to call a class of deformed Feynman integrals as twisted Feynman integrals, where the integrand has an additional exponential factor linear in loop momenta. [...]

Quirks Live in Cool Universes / Asadi, Pouya (UC, Santa Cruz) ; Kribs, Graham D. (Oregon U. ; CERN) ; Luty, Markus A. (UC, Davis, QMAP)
We demonstrate that cosmological observations place strong bounds on the reheat temperature $T_\text{RH}$ of the Standard Model (SM) in minimal models of `quirks' -- heavy fermions transforming under the SM gauge group together with a new non-Abelian gauge interaction with a confinement scale far below the mass of the fermions. [...]

Probing invisible particles with charm / Hiller, Gudrun (Dortmund U. ; CERN) ; Suelmann, Dominik (Dortmund U.)
We point out opportunities to probe invisible particles, left- and right-handed neutrinos, axion-like particles (ALPs) and dark photons $(Z^\prime)$ with rare decays of charm hadrons. [...]

Euclid preparation. Review of forecast constraints on dark energy and modified gravity / Euclid Collaboration
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the Universe and the formation of structures. [...]

Commissioning of proANUBIS: A proof-of-concept detector for the ANUBIS experiment / ANUBIS Collaboration
Long-lived particles (LLPs), predicted by various extensions of the Standard Model (SM), have become a key focus of the contemporary search programme for physics beyond the SM. [...]

A comprehensive analysis of the $B^0\to K^{*0}μ^+μ^-$ decay / LHCb Collaboration
An analysis of the $B^{0}\rightarrow K^{*0}(\to K^+ π^-)μ^{+}μ^{-}$ decay is presented using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 8.4 fb$^{-1}$. [...]

F-theorem for Quantum Field Theories in Anti-de Sitter Space / Bason, Davide (Tsinghua U., Beijing) ; Copetti, Christian (Oxford U., Inst. Math.) ; Di Pietro, Lorenzo (Trieste U. ; INFN, Trieste) ; Ji, Ziming (Northeastern U.) ; Komatsu, Shota (CERN)
We introduce a regularized free energy $\mathcal{F}_{\text{AdS}}$ for massive quantum field theories (QFTs) on Anti-de Sitter space (AdS). [...]

A Composite Theory of Higgs and Flavour / Davighi, Joe ; Isidori, Gino
We introduce a composite Higgs model in which a flavour deconstructed gauge group is embedded in the strong sector. [...]

Prompt Searches for Very-High-Energy γ-Ray Counterparts to IceCube Astrophysical Neutrino Alerts / FACT Collaboration
The search for sources of high-energy astrophysical neutrinos can be significantly advanced through a multi-messenger approach, which seeks to detect the gamma rays that accompany neutrinos as they are produced at their sources. [...]
