As Gravitational waves were detected in 2017 by LIGO and VIRGO collaborations, it gained a lot of interest. In this project, we find the final mass and spin of the RBH using a mathematical model. After analyzing the data from GW190521, we find that the final spin is 0.77 and mass of the system is 141.17M. It is also found that they are inversely proportional and the data sets fit the model...
The Electron-Ion Collider is a future collider planned to be built at BNL in about 2030. It will provide physicists with high luminosity and highly polarized beams with a wide range of nuclei species at different energies, covering an extensive kinematic range. The EIC physical goals include measuring the generalized parton distribution from Deeply Virtual Compton Scattering (DVCS) and Deeply...
The top-quark Yukawa coupling $y_t$ is the strongest interaction of the Higgs boson in the Standard Model (SM) with $y_t \sim 1$. Due to its magnitude, it plays a central role in Higgs phenomenology in the SM and would be most sensitive to physics beyond the Standard Model. The top Yukawa can be directly measured at the LHC via top pair production in association with a Higgs boson...
In our view, the descriptio of Higgs boson in Standard Model has the following problems:
• The Higgs boson in Standard Model has the weak isospin of ½. At the same time, the analysis of experimental data on its decay channels [1] lead to a conclusion that all of the observed final states of the decay products have integer weak isospin. Since the Lagrangian of the Standard Model is symmetric...
General relativity with fermions has two independent symmetries: general coordinate invariance and local Lorentz invariance. General coordinate invariance is implemented by the Levi-Civita connection and by Cartan's tetrads both of which have as their action the Einstein-Hilbert action. It is suggested here that local Lorentz invariance is implemented not by a combination of the Levi-Civita...
The technique of semi-supervision can be used in searches for new physics where the signal plus background regions are not labelled. We employ semi-supervision but this technique has over-fitting issues. We resort to GANs to mimic a Monte Carlo (MC) simulation which is very expensive computationally in order to perform toy MC studies. We propose Generative Adversarial Networks (GANs) as our...
We present a formalism that resums threshold enhanced large logarithms to all orders in perturbation theory for the production of a pair of leptons in Drell-Yan process and of Higgs boson in gluon fusion as well as in bottom quark annihilation. As for the inclusive cross-section, the rapidity distribution is a prime candidate to benefit from threshold resummation, hence we apply the same...
A search for Higgs Boson pair production via vector boson fusion and decaying to b-quarks and WW/ZZ/𝛕𝛕 final states is underway uses the Run-2 dataset collected by ATLAS at √s = 13 TeV, corresponding to 139 fb of 2015-2018 providing a completely new signature in the Higgs sector. This search can give constraints on the parameters of the Higgs coupling with vector bosons, especially the...
The Belle II detector is situated inside an electron-positron collider in Japan called SuperKEKB and has been in operation since 2019. Like other B Factories of the past, Belle II is partly responsible for performing rare B decay analyses, and in such analyses, the variable $E_\mathrm{extra}$ is an important tool for signal yield extraction and background suppression, with many key analyses...
The Realism [1], which is based on the properties of classical objects can be violated in quantum world. Assumption that observables of the system can jointly exist (Classical realism) and Locality can be wrong in Quantum Mechanics [2].
Test of the Realism can be done with Wigner inequalities [3]. There should be three dichotomous variables in Wigner inequalities and these inequalities...
Recent measurements at the Large Hadron Collider allow for a robust and precise characterisation of the electro-weak interactions of the top quark. We present the results of a global analysis at next-to-leading order precision including LHC, LEP/SLD and Tevatron data in the framework of the Standard Model Effective Field Theory. We include a careful analysis of the impact of correlations among...
The topic is focused on the properties of η meson by following the approach
of the chiral SU(3) model. We are dealing with the Lagrangian density of chiral
SU(3) model that has exchange vector and scalar field terms and a hypothetical
glueball field χ, to incorporate the scale invariance property of QCD. This phenomenological model explains effective meson interactions in the chiral limit...
