DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/54/">C
 osmology of Axion Rotation</a>\nby Keisuke Harigaya (University of Chicago
 ) as part of NHETC Seminar\n\n\nAbstract\nWe will introduce new cosmologic
 al dynamics of the QCD axion\, where the axion field rotates in field spac
 e. Axion dark matter may be produced from the kinetic energy of the rotati
 on and the required axion decay constant is much below the prediction of t
 he conventional evolutions. The angular momentum of the rotation is transf
 erred into baryon asymmetry through baryon number violating interactions. 
 We discuss the electroweak sphaleron process and some beyond-standard mode
 l processes and predictions on the parameters of each theory.\n
