Beyond the Standard Model Phenomenology 1
- Vedran Brdar (Oklahoma State University (US))
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...
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...
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.
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...
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...
