The Role and Detectability of the Charm Contribution to Ultra High Energy Neutrino Fluxes
Raj Gandhi, Abhijit Samanta, Atsushi Watanabe
It is widely believed that charm meson production and decay may play an important role in high energy astrophysical sources of neutrinos, especially those that are baryon-rich, pro…
Minimal Seesaw Textures with Two Heavy Neutrinos
Srubabati Goswami, Atsushi Watanabe
We systematically analyze the Dirac and the Majorana mass matrices in seesaw models with two heavy right-handed neutrinos. We perform thorough classification of the vanishing matri…
Twisted Flavors and Tri/bi-Maximal Neutrino Mixing
Naoyuki Haba, Atsushi Watanabe, Koichi Yoshioka
A new framework for handling flavor symmetry breaking in the neutrino sector is discussed where the source of symmetry breaking is traced to the global property of right-handed neu…
Minimal archi-texture for neutrino mass matrices
Atsushi Watanabe, Koichi Yoshioka
The origin of the observed masses and mixing angles of quarks and leptons is one of imperative subjects in and beyond the standard model. Toward a deeper understanding of flavor st…
Asymmetry and Minimality of Quark Mass Matrices
Nobuhiro Uekusa, Atsushi Watanabe, Koichi Yoshioka
We systematically investigate general forms of mass matrices for three-generation up and down quarks, including asymmetrical ones in generation space. Viable zero matrix elements a…
