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"...

In recent years, an alternative to the standard ฮCDM model has emerged known as Fuzzy Dark Matter (FDM). We discuss how FDM, characterized by ultra-light bosonic particles with masses on the order of 10^{-22}eV, arises within String Theory constructions, particularly those involving axion-like fields. We study how FDM influences structure formation on astrophysical scales, leading to a...

In the Standard Model of particle physics, each generation of fermion is replicated in all quantum numbers but with a higher mass in the next generation. Three chiral generations have been found so far. Using the replication property as an inspiration we look for fractal geometries to be behind the SM flavor mixing. A realistic model based on Sierpinski geometry on a deconstruction model...

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...

Although in the conventional quark model the hadrons are classified either mesons or baryons, the quantum chromodynamics (QCD) allows other types of hadron states, so-called exotic hadron states, such as tetraquarks, pentaquarks, glueballs, hybrid states, etc. Studies of exotic hadrons therefore could provide crucial information for understanding the detailed structure of strong interactions....

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...

The stress energy tensor we all know is related to the existence of a metric. But the metric is not the only character we can take into account when studying a theory of gravity. We can also consider an independent connection. If we do so we will have the hypermomentum tensor in the game too. This can be related to quantities such as torsion and non metricity. What is the role of these...

This study explores the potential existence of traversable wormholes influenced by a global monopole charge within the $f(Q)$ gravity framework. To elucidate the characteristics of these wormholes, we conducted a comprehensive analysis of wormhole solutions employing three different forms of redshift function under a linear $f(Q)$ model. Wormhole shape functions were derived for barotropic,...

We investigate mass hierarchies in models with modular flavor symmetries. Several key conclusions arise from the observation that the determinants of mass matrices are one-dimensional vector-valued modular forms. Under some fairly general assumptions, we demonstrate that achieving hierarchical fermion masses requires the VEV of the modulus to be located near one of the critical points in...

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...
