We implement a test of MOND and Verlinde's Emergent Gravity using the galaxy cluster SMACS J0723-7327, which has been recently imaged using the eROSITA X-ray telescope as well as with JWST. We test MOND using two independent methods. The first method involves comparing the dynamical MOND mass and baryonic mass, while the second method entails a comparison of the MOND-estimated temperature with...

Tracing out degrees of freedom is a standard technique in quantum field theory to isolate the relevant aspects of a system. In this study, we investigate cases where different approaches to tracing out degrees of freedom lead to non-trivial results and implications. Specifically, we consider the vacuum state of a massless scalar field in Minkowski spacetime, partitioned into two Rindler...

A non-classical inflaton which is minimally coupled to the semiclassical theory of gravity in the flat Friedmann-Robertson-Walker (FRW) universe. Using a Coherent Squeezed Vacuum State, we analyzed the validity of the semiclassical theory of gravity by computing density fluctuations in the oscillatory phase of the inflaton. The current study is for density fluctuations of non-classical...

Ultralight Axion Like Particles (ALPs) can mediate a macroscopic force with long-range monopole-dipole interactions between the Earth and the Sun, if the Earth is treated as a polarized source. Due to the geomagnetic field, there exists an estimated $10^{42}$ polarized electrons within the Earth. These electrons, in a polarized state, can interact with the unpolarized nucleons in the Sun,...

The gap between the experimental average and standard model value for the muon anomalous magnetic moment is a direct hint of fields beyond the standard model. In this work, we investigate the contribution of heavy right-handed neutrino for muon (g - 2) in left-right symmetric model. Simultaneously, we checked the dominance(type-I and type-II) patterns for the Majorana type Yukawa coupling...

Dark matter (DM) is a fascinating subject in Astrophysics and Cosmology. While its exact nature remains elusive, its presence in the universe is inferred through various observational evidences such as galaxy rotation curves, velocity dispersions, gravitational lensing etc. Dark matter halos develop in the universe and subsequently facilitate galaxy formation by accumulating protons. Neutron...

We investigate different classes of models, in which the dark matter candidate arises as a hadronic state of dark constituent quarks, which are charged under both the new confining dark gauge group and the standard model. Specifically, we focus on the case of quarks in the fundamental representation of SU(N), which are heavier than the dark QCD confinement scale. Recent literature has...

Neutrino experiments often utilize heavy nuclear targets to achieve high-statistics neutrino-nucleus interaction event rates. However, this approach introduces systematic uncertainties in oscillation parameters due to nuclear effects and cross-section uncertainties. A precise understanding of neutrino-nucleus interactions is thus crucial for accurately determining oscillation parameters. The...

In this study, we explore the impact of texture zero on the neutrino mass matrix, focusing on their ability to constrain unknown parameters such as mixing angles, Dirac and Majorana phases, and mass eigenstates. We investigate one-zero texture within the framework of generalized CP symmetry associated with the complex tribimaximal matrix. By combining these approaches, we derive predictive...

The quest for precise measurements of the muon's magnetic moment, prompted by the observed discrepancy between theoretical and experimental results by other experiments worldwide, is the motivation of the upcoming muon g-2/EDM experiment at J-PARC.

The Hyper-Kamiokande (Hyper-K) is a next-generation long baseline neutrino experiment. One of its primary physics goals is to measure neutrino oscillation parameters precisely, including CP-asymmetry measurement. As the conventional νµ beam from the J-PARC neutrino production baseline contains only 1.5% of the electron neutrino interaction of the total, it is very challenging to measure...

The production cross sections of the Standard Model Higgs boson decaying into a pair of W bosons have been measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis targets Higgs bosons produced through gluon-gluon fusion, vector boson fusion, and in association with a vector boson. Candidate events were selected based on the presence of at least two charged...

We investigate two most popular beyond standard Model scenarios explaining neutrino mass and dark matter. These scenarios can potentially explain the first order phase transitions, which is required for electroweak baryogenesis. The first scenario is Type-II seesaw, and we show that perturbative constraints can be strong enough to rule out most of the parameters for the first order phase...

The $SU(2)_L$ triplet scalar extension of the Standard Model offers interesting collider phenomenology. The minimal extension with custodial symmetry demands one real triplet scalar with a hypercharge quantum number zero, and one complex triplet scalar with a hypercharge quantum number one, in addition to the Standard Model Higgs doublet. This model is dubbed as extended Georgi-Machacek...

In this analysis, $\Xi_{cc}^{++}$ is considered as a bound state of $cc$ diquark and a $u$ quark.

We present a search for the yet-unobserved B→Dηπ decay at Belle and Belle II. This search aims to provide insights into the semileptonic gap, which refers to the deficit in the sum of the branching fractions of known exclusive decays compared to the measured inclusive b→cℓν branching fraction. Common models addressing this deficit suggest the existence of B→Dηℓν decays with a branching...

Warm inflation differs from other forms of inflation primarily in that it makes the assumption that radiation and inflaton exist and interact throughout the inflationary process. After the warming process, energy moves from the inflaton to the radiation as a result of the...
