The Spectrum of Global Axion Strings
Mathieu Kaltschmidt, Javier Redondo, Ken'ichi Saikawa +1
The post-inflationary Peccei-Quinn (PQ) symmetry breaking scenario provides a unique opportunity to pinpoint the QCD axion dark matter mass, which is a crucial input for laboratory…
Non-thermal Axion Dark Radiation and Constraints
Anupam Mazumdar, Saleh Qutub, Ken'ichi Saikawa
The Peccei-Quinn mechanism presents a neat solution to the strong CP problem. As a by-product, it provides an ideal dark matter candidate, "the axion", albeit with a tiny mass. Axi…
Affleck-Dine baryogenesis with R-parity violation
Tetsutaro Higaki, Kazunori Nakayama, Ken'ichi Saikawa +2
We investigate whether the baryon asymmetry of the universe is explained in the framework of the supersymmetric extension of the Standard Model with R-parity violating interactions…
