The Amplitude for Classical Gravitational Scattering at Third Post-Minkowskian Order / Bjerrum-Bohr, N.E.J. ; Damgaard, P.H. ; Planté, L. ; Vanhove, P.
We compute the scattering amplitude for classical black-hole scattering to third order in the Post-Minkowskian expansion, keeping all terms needed to derive the scattering angle to that order from the eikonal formalism. [...]

Complete Set of Feynman Rules for Scalar Leptoquarks / Crivellin, Andreas ; Schnell, Luc
Leptoquarks (LQs) have attracted increasing attention within recent years, mainly since they can explain the flavor anomalies found in $R(D^{(*)})$, $b \rightarrow s \ell^+ \ell^-$ transitions and the anomalous magnetic moment of the muon. [...]

r-Process Radioisotopes from Near-Earth Supernovae and Kilonovae / Wang, Xilu ; Clark, Adam M. ; Ellis, John ; Ertel, Adrienne F. ; Fields, Brian D. ; Liu, Zhenghai ; Miller, Jesse A. ; Surman, Rebecca
The astrophysical sites where r-process elements are synthesized remain mysterious: it is clear that neutron-star mergers (kilonovae, KNe) contribute, and some classes of core-collapse supernovae (SNe) are also likely sources of at least the lighter r-process species. [...]

Quantum spectral problems and isomonodromic deformations / Bershtein, Mikhail ; Gavrylenko, Pavlo ; Grassi, Alba
We develop a self-consistent approach to study the spectral properties of a class of quantum mechanical operators by using the knowledge about monodromies of $2\times 2$ linear systems (Riemann-Hilbert correspondence). [...]

Axion Dark Matter: What is it and Why Now? / Chadha-Day, Francesca (Durham U., IPPP) ; Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Marsh, David J.E. (King's Coll. London)
The axion has emerged in recent years as a leading particle candidate to provide the mysterious dark matter in the cosmos, as we review here for a general scientific audience. [...]

(Vienna U.) et al.
We report some highlights from the ARIES APEC workshop on ``Storage Rings and Gravitational Waves'' (SRGW2021), held in virtual space from 2 February to 18 March 2021, and sketch a tentative landscape for using accelerators and associated technologies for the detection or generation of gravitational waves..

Dark matter and the early Universe: a review / Arbey, A. (IP2I, Lyon ; CERN ; IUF, Paris) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris)
Dark matter represents currently an outstanding problem in both cosmology and particle physics. In this review we discuss the possible explanations for dark matter and the experimental observables which can eventually lead to the discovery of dark matter and its nature, and demonstrate the close interplay between the cosmological properties of the early Universe and the observables used to constrain dark matter models in the context of new physics beyond the Standard Model..
