Leptogenesis in a seesaw model with Fritzsch type lepton mass matrices
Y. H. Ahn, Sin Kyu Kang, C. S. Kim +1
We investigate how the baryon asymmetry of our universe via leptogenesis can be achieved within the framework of the seesaw model with Fritzsch type lepton mass matrices proposed b…
Correlation between lepton flavor violation and B_{(d,s)} - \bar{B}_{(d,s)} mixing in SUSY GUT
Kingman Cheung, Sin Kyu Kang, C. S. Kim +1
Motivated by the recent measurements of the B_s-\bar{B}_s mass difference from the D0 and CDF collaborations, we probe new physics effects in the B_q-\bar{B}_q mixing within the co…
Symmetry and Radiatively Generated Leptogenesis
Y. H. Ahn, Sin Kyu Kang, C. S. Kim +1
We consider a symmetry in neutrino sectors realized at GUT scale in the context of a seesaw model. In our scenario, the exact symmetry realized in the basis where the c…
Phased Breaking of mu-tau symmetry and Leptogenesis
Y. H. Ahn, Sin Kyu Kang, C. S. Kim +1
Non-vanishing U_{e3} has been theoretically related to a certain flavor symmetry breaking in the neutrino sector. We propose a scenario to break the mu-tau symmetry so as to accomm…
Systematic Investigation of Possibilities for New Physics Effects in b --> s Penguin Processes
C. S. Kim, Y. J. Kwon, Jake Lee +1
Although recent experimental results in b-->s penguin process seem to be roughly consistent with the standard model predictions, there may be still large possibilities of new physi…
The intrinsic and oscillated astrophysical neutrino flavor ratios
H. Athar, C. S. Kim, Jake Lee
The pp interactions taking place in the cosmos around us are a source of the astrophysical neutrinos of all the three flavors. In these interactions, the electron and the muon neut…
