Probing New Physics in Charm Couplings with FCNC
Xiao-Gang He, Jusak Tandean, G. Valencia
Low-energy experiments involving kaon, B-meson, D-meson, and hyperon flavor-changing neutral transitions have confirmed the loop-induced flavor-changing neutral current (FCNC) pict…
Unified triminimal parametrizations of quark and lepton mixing matrices
Xiao-Gang He, Shi-Wen Li, Bo-Qiang Ma
We present a detailed study on triminimal parametrizations of quark and lepton mixing matrices with different basis matrices. We start with a general discussion on the triminimal e…
Lepton FCNC in Type III Seesaw Model
Xiao-Gang He, Sechul Oh
In Type III seesaw model, there are tree level flavor changing neutral currents (FCNC) in the lepton sector, due to mixing of charged particles in the leptonic triplet introduced t…
Neutral Higgs boson pair production in photon-photon annihilation in the Two Higgs Doublet Model
Abdesslam Arhrib, Rachid Benbrik, Chuan-Hung Chen +1
We study double Higgs production in photon-photon collisions as a probe of the new dynamics of Higgs interactions in the framework of two Higgs Doublet Models. We analyze neutral H…
ATIC/PAMELA anomaly from fermionic decaying Dark Matter
Chuan-Hung Chen, Chao-Qiang Geng, Dmitry V. Zhuridov
We demonstrate that an economical two Higgs doublet model can explain the electron and positron excesses in the recent ATIC and PAMELA experiments by the three body decays of the d…
U_A(1) Anomaly in Hot and Dense QCD and the Critical Surface
Jiunn-Wei Chen, Kenji Fukushima, Hiroaki Kohyama +2
We discuss the chiral phase transition in hot and dense QCD with three light flavors. Inspired by the well known fact that the U_A(1) anomaly could induce first order phase transit…
