  1. 24. Free Regional Computational Resources for High-Energy Physics and Astroparticle Research: High-Performance Computing and Distributed Systems
    Terrance Figy (Wichita State University)
    02/11/2024, 16:20

    In this presentation, I will elucidate the diverse array of cutting-edge computing resources available for unrestricted use. Noteworthy examples include the BeoCat High-Performance Computing (HPC) system at Kansas State University, the formidable Pete Supercomputer at Oklahoma State University, the highly efficient BeoShock HPC system at Wichita State University, and the Open Science Grid...

  2. 15. Momentum shift and on-shell recursion relation for electroweak theory
    Ishmam Mahbub (University of Minnesota Twin Cities)
    02/11/2024, 16:30

    We study the All-Line Transverse (ALT) shift which we developed for on-shell recursion of amplitudes for particles of any mass. We discuss the validity of the shift for general theories of spin $\leq$ 1, and illustrate the connection between Ward identity and constructibility for massive spin-1 amplitude under the ALT shift. We apply the shift to the electroweak theory, and various four-point...

  3. 22. Domain walls of string theory axions
    Saurav Das (Washington University in St. Louis)
    02/11/2024, 16:48

    String theory strings can magnetically source axions or axion like particles. The axions get potential from string instantons and can produce domain walls. The string-domain wall network can be stable for a long time. The later collapse of the domain walls produce more than one type of axion mass eigenstates apart from gravitational waves.

  4. 26. Right-Handed Neutrino Masses from the Electroweak Scale
    Wenjie Huang
    02/11/2024, 17:06

    Heavy right-handed neutrinos are highly motivated due to their connection with the origin of neutrino masses via the seesaw mechanism. If the right-handed neutrino Majorana mass is at or below the weak scale, direct experimental discovery of these states is possible in accelerator experiments. However, there is no a priori reason to prefer such light right-handed neutrinos since the Majorana...

  5. 7. Enhanced Dark Matter Abundance in First-Order Phase Transitions
    Cash Hauptmann (University of Nebraska - Lincoln)
    02/11/2024, 17:24

    We propose a novel scenario to obtain the correct relic abundance for thermally under-produced dark matter. This scenario utilizes a strongly first-order phase transition at temperature $T_{\rm PT}$ that gives rise to dark matter mass $m$. Freeze-out in the broken phase can yield the desired abundance in the entire region currently allowed by observational bounds and theoretical constraints...

  6. 29. Flavored Resonant Leptogenesis in a Type-I Two Higgs Doublet Model
    Kairui Zhang (University of Oklahoma-Norman)
    02/11/2024, 17:42

    In this work, we explore flavored resonant leptogenesis within the framework of a Type-I Two Higgs Doublet Model (2HDM), where the second Higgs doublet couples exclusively to right-handed neutrinos. We investigate how the flavor effects and flavor decoherence influence the generation of baryon asymmetry in the early universe. This model allows for a reduction in the mass scale of the...
