More axions from diluted domain walls
Keisuke Harigaya, Lian-Tao Wang
We consider the scenario in which the Peccei-Quinn symmetry breaking is followed by a period of inflation. A particularly interesting case is that the string-domain wall network pr…
TF08 Snowmass Report: BSM Model Building
Patrick J. Fox, Graham D. Kribs, Hitoshi Murayama +53
We summarize the state of Beyond the Standard Model (BSM) model building in particle physics for Snowmass 2021, focusing mainly on several whitepaper contributions to BSM model bui…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
Dark Radiation Constraints on Heavy QCD Axions
David I. Dunsky, Lawrence J. Hall, Keisuke Harigaya
The naturalness problem of PQ symmetry motivates study of the heavy QCD axion, with masses 1 MeV generated at scales above the QCD scale, and low values of the PQ symmetry…
New Ideas in Baryogenesis: A Snowmass White Paper
Gilly Elor, Julia Harz, Seyda Ipek +21
The Standard Model of Particle Physics cannot explain the observed baryon asymmetry of the Universe. This observation is a clear sign of new physics beyond the Standard Model. Ther…
Naturalness and the muon magnetic moment
Nima Arkani-Hamed, Keisuke Harigaya
We study a predictive model for explaining the apparent deviation of the muon anomalous magnetic moment from the Standard Model expectation. There are no new scalars and hence no n…
