We present a supersymmetric Pati-Salam model with small representations as a potential candidate for physics beyond the Standard Model. The model features a Higgs sector with bifundamental fields $H_R+\bar H_R=(4,1,2)+(\bar 4,1,2)$, $H_L+\bar H_L=(4,2,1)+(\bar 4,2,1)$ as well as a pair of bi-doublet fields $h_a=(1,2,2)$ where $ a=1,2$, with three families of fermions accommodated in $...

We propose a novel approach to calculate the false vacuum decay rate, which goes beyond the saddle-point approximation when large thermal fluctuations appear. Utilizing the extension of the Wigner function in quantum field theory, we numerically calculate the decay rate of the false vacuum through functional integral. We observe that the decay rate for the thermal fluctuation scenarios and its...

We propose a parametrization of neutrino masses and mixing in the minimal seesaw model (MSM). The MSM, which introduces two heavy sterile neutrinos, is the minimal extension of the Standard Model in addressing the tiny masses of active neutrinos. The parametrization includes 11 free parameters: 6 neutrino oscillation parameters (2 mass-squared differences $\Delta m^2_{21}$, $\Delta m^2_{31}$,...

GUTs unify quarks and leptons into same representations and predict correlations between their masses and mixing. We take new data of JUNO and perform numerical scans to explore the flavor space compatible with data in SO(10) GUTs. The quark-lepton correlation shows the preference of normal ordering for light neutrino masses, predicts favored region of the CP-violating phase in neutrino...

Although the Standard Model has achieved remarkable success, its limitations motivate physicists to continuously explore new fundamental particle theories. Among the numerous candidate theories, Grand Unified Theories (GUTs) have attracted significant attention due to their simplicity and potential to unify the three fundamental interactions.
We present a detailed study of the running of...
