Description

*Unlike usual "NAPP Seminar", this seminar will be held in #23-317. Please check.  

 

*Speaker : Jun-Sik Yoo (PhD Program at Stony Brook University)

 

*Abstract :

Proton decay is one of possible signatures of baryon number violation, which has to exist to explain the baryon asymmetry and the existence of nuclear matter. Proton decays must be mediated through effective low-energy baryon number violating operators made of three quarks and a lepton. We calculate matrix elements of these operators between an initial proton and various final pseudoscalar mesons using the three-point function method. For the first time, we use the 2+1 dynamical flavor domain wall fermions at the physical point for the calculation over the three source-sink separations.)
