Prospects of future MeV telescopes in probing weak-scale Dark Matter

Marco Cirelli, Arpan Kar

Galactic weak-scale Dark Matter (DM) particles annihilating into lepton-rich channels not only produce gamma-rays via prompt radiation but also generate abundant energetic electrons and positrons, which subsequently emit through bremsstrahlung or inverse Compton scattering (collectively called `…

Bispectrum at NLO in single field inflation: conservation and squeezed limit

Ignatios Antoniadis, Auttakit Chatrabhuti, Jules Cunat, Hiroshi Isono

In a recent paper, we computed the bispectrum of primordial density perturbations in CMB to second order in the slow-roll parameters of single field inflation, and found logarithmic infrared contributions that diverge in both large physical distances and squeezed limit where one momentum vanishes.…

Shift orbifolds, decompactification limits, and lattices

Dan Israel, Ilarion V Melnikov, Yann Proto

We describe the general shift orbifold of a Narain CFT and use this to investigate decompactification limits in the heterotic Narain moduli space. We also comment on higher rank theories and describe some applications to the CFT based on the Leech lattice and its shift orbifolds.

Recasting the ATLAS search for displaced hadronic jets in the ATLAS calorimeter with additional jets or leptons using surrogate models

Louie Corpe, Abdelhamid Haddad, Mark Goodsell

This note describes the validation of a new form of re-interpretation material provided by an ATLAS search for hadronically-decaying neutral long-lived particles in association with jets or leptons, using the full Run-2 dataset. This reference ATLAS analysis provided a set of machine-learning-based…
