Seesaw models of neutrino masses and leptogenesis are oft accompanied by LeptoQuarks (LQs) in various top down UV completions like Pati-Salam and $SO(10)$ and consider their impact on thermal leptogenesis. We demonstrate a minimal possibility of achieving successful leptogenesis with just an additional $(3,2,\frac{1}{6})$ "doublet leptoquark" to the standard two Right Handed Neutrinos (RHNs)...
String compactifications generically predict the presence of light scalar moduli, whose late-time coherent oscillations and decay induce an early matter-dominated era, often in tension with constraints from Big Bang Nucleosynthesis (BBN) and Cosmic Microwave Background (CMB) observations. Their decay can both reheat the visible sector and populate hidden sectors, potentially contributing to...
I will present a study of quark and lepton masses in a universal seesaw
with modular A4 symmetry. Light fermion masses arise from mixing with
heavy vector-like partners. A SUSY setup with gCP and minimal Z2 is
adopted in this model. The global fit uses 17 parameters in total—the
complex τ plus 15 real parameters—to describe 18 observed quantities
across the CKM and PMNS sectors. The...
Understanding how the Higgs boson interacts with itself and with other particles remains one of the central goals of particle physics. In this project, I investigate Higgs boson pair production through the vector boson fusion (VBF HH) process to explore possible deviations from the Standard Model. Using Herwig and VBFNLO event generators, I simulate proton–proton collisions and study how...
