The axion solution to the strong CP problem is closely entwined with the flavor structure of the standard model. So our model attempts at explaining the Flavor puzzle through the a gauged abelian Frogatt Nielsen mechanism and thereby automatically end up with a "quality axion" as the result of a residual anomalous $U(1)_{PQ}$ symmtery. This is achieved in a DFSZ like scenario with a "Flavon"...
Generalized global symmetries are present in theories of particle physics, and understanding their structure can give insight into these theories and UV completions thereof. We will identify non-invertible chiral symmetries in certain flavorful Z' extensions of the Standard Model, and this will lead us to interesting nonperturbative effects in theories of gauged non-Abelian flavor. For the...
We construct a brane world SU(5) Grand Unified Theory in five-dimensional space-time by using domain walls. The SU(5) gauge symmetry is broken down to the Standard Model gauge group by a domain wall configuration. Matters are localized around the domain walls by the so-called Jackiew-Rebbi mechanism while the gauge fields are localized by the non-minimal coupling between the gauge fields and...
Curvaton mechanism provides an alternative way to explain the origin of the observed primordial scalar fluctuations in the Cosmic Microwave Background (CMB) radiation. In this scenario, the curvaton is a scalar field which nearly remains frozen during inflation but produces isocurvature perturbations. It starts to evolve after the end of inflation, and at the time of it's decay it converts the...
We study thermal and non-thermal resonant leptogenesis in a general setting where a heavy scalar $\phi$ decays to right-handed neutrinos (RHNs) whose further out-of-equilibrium decay generates the required lepton asymmetry. Domination of the energy budget of the Universe by the $\phi$ or the RHNs alters the evolution history of the primordial gravitational waves (PGW) of inflationary origin,...
The vGeN experiment is performed at the Kalinin Nuclear Power Plant at a distance of 11 m from the center of the reactor core. The goals of the experiment include observation of coherent elastic scattering of reactor antineutrinos off nuclei (CEvNS) and search for the magnetic moment of antineutrino (NMM) using a 1.4 kg low-threshold germanium detector. Based on the data from September 2022 to...
We propose an experiment focused on designing and developing a liquid organic scintillation detector, along with its characterization using a photomultiplier tube for scintillation counting and high-energy particle detection. The experiment aims to optimize conditions for long-term stability, low background noise, high gain, and a high signal-to-noise ratio. We will also examine the system's...
