27. Parity solution to the Strong CP-problem in Pati-Salam Model​

We aim to have a solution for the strong CP problem using softly broken Parity invariance in the context of Quark-Lepton Unified (Pati-Salam) Model where fermions acquire "see-saw" masses. The inclusion of vector-like fermions helps realize the see-saw mass mechanism. The smallness of the Physical Theta-parameter ($\bar\theta$) arises from the experimental bound of the electric dipole moment...

Precision measurements of Standard Model (SM) parameters are valuable multipurpose probes for heavy new physics and check the consistency of the Standard Model. We propose a new purpose for precision SM measurements: constraining light new physics that can impact kinematic distributions used in measuring SM parameters. To illustrate this, we consider the W mass measurement, where new physics...

Axions with masses around $\mu eV$ could account for dark matter in the universe. However, their small couplings with SM particles make it demanding to detect their signatures. In the presence of background photons, the decay rate of an axion to two photons is increased due to Bose enhancement, which could enhance the decay rate by a factor of millions. In this talk, we will discuss axion...

11. Fermion mass, Axion dark matter, and Leptogenesis in SO(10) GUT

SO(10) grand unified theory with minimum parameters in the Yukawa sector employs the Peccei-Quinn symmetry that solves the strong CP problem. Such an economical Yukawa sector is highly appealing and has been extensively studied in the literature. However, when the running of the renormalization group equations of the Yukawa couplings are considered, this scenario shows somewhat tension with...
