Loop Dominated Signals from Neutrino Portal Dark Matter / Patel, Hiren H. ; Profumo, Stefano ; Shakya, Bibhushan
We study scenarios where loop processes give the dominant contributions to dark matter decay or annihilation despite the presence of tree level channels. [...]

A deep neural network for simultaneous estimation of b jet energy and resolution / CMS Collaboration
We describe a method to obtain point and dispersion estimates for the energies of jets arising from b quarks produced in proton-proton collisions at an energy of $\sqrt{s} = $ 13 TeV at the CERN LHC. [...]

Supersymmetric Proton Decay Revisited / Ellis, John ; Evans, Jason L. ; Nagata, Natsumi ; Olive, Keith A. ; Velasco-Sevilla, Liliana
Encouraged by the advent of a new generation of underground detectors---JUNO, DUNE and Hyper-Kamiokande---that are projected to improve significantly on the present sensitivities to various baryon decay modes, we revisit baryon decay in the minimal supersymmetric SU(5) GUT. [...]

AION: An Atom Interferometer Observatory and Network / Badurina, L. (King's Coll. London) ; Bentine, E. (U. Oxford (main)) ; Blas, D. (King's Coll. London) ; Bongs, K. (Birmingham U., UK) ; Bortoletto, D. (U. Oxford (main)) ; Bowcock, T. (U. Liverpool (main)) ; Bridges, K. (U. Liverpool (main)) ; Bowden, W. (Teddington, Natl. Phys. Lab ; Imperial Coll., London) ; Buchmueller, O. (Imperial Coll., London) ; Burrage, C. (U. Nottingham) et al.
We outline the experimental concept and key scientific capabilities of AION (Atom Interferometer Observatory and Network), a proposed UK-based experimental programme using cold strontium atoms to search for ultra-light dark matter, to explore gravitational waves in the mid-frequency range between the peak sensitivities of the LISA and LIGO/Virgo/ KAGRA/INDIGO/Einstein Telescope/Cosmic Explorer experiments, and to probe other frontiers in fundamental physics.

Search for a narrow resonance lighter than 200 GeV decaying to a pair of muons in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
A search is presented for a narrow resonance decaying to a pair of oppositely charged muons using $\sqrt{s} = $ 13 TeV proton-proton collision data recorded at the LHC. [...]

Searches for additional Higgs bosons at CMS / Tao, Junquan (Beijing, Inst. High Energy Phys.) /CMS Collaboration
Direct searches for additional Higgs bosons at CMS are presented. The searches for heavy neutral Higgs bosons, charged Higgs bosons and light neutral Higgs bosons are performed using proton-proton collision data at $\sqrt{s}=13$ TeV collected by the CMS detector. [...]

Probing the scale of grand unification with gravitational waves / Buchmuller, Wilfried ; Domcke, Valerie ; Murayama, Hitoshi ; Schmitz, Kai
The spontaneous breaking of $U(1)_{B-L}$ around the scale of grand unification can simultaneously account for hybrid inflation, leptogenesis, and neutralino dark matter, thus resolving three major puzzles of particle physics and cosmology in a single predictive framework. [...]
