  1. 16. A path to leptoquark aided leptogenesis
    Sai Charan Chandrasekar (PhD Student at Oklahoma State University)
    16/11/2025, 09:00

    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)...

  2. 13. From Stringy Compactifications to Dark Universe: A "Two Birds, One Stone'' Approach
    Aditi Shahani (University of Oklahoma)
    16/11/2025, 09:18

    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...

  3. 19. Quark and Lepton Masses in Universal Seesaw Models with Modular A4 Symmetry
    Murshed Alam (Oklahoma State University)
    16/11/2025, 09:36

    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...

  4. 8. Investigating Higgs Coupling Modifications in Vector Boson Fusion Higgs Pair Production.
    Tunde Kushimo (Wichita State University)
    16/11/2025, 09:54

    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...

  5. 25. Sterile Neutrino Dark Matter Production via Active–Sterile Non-Standard Interactions
    Aaroodd UR
    16/11/2025, 10:12

    Sterile neutrinos are compelling dark matter candidates, but production solely from active-sterile oscillations is excluded by astrophysical observations. Non-standard self-interactions in either active or sterile sector can modify production to some extent. Here we propose a novel solution where scalar-mediated non-standard interactions between active and sterile neutrinos generate new...
