Aspects of Heavy Supersymmetry
The recent discovery of a Higgs boson with a mass around 125 GeV, taken together with experimental results from flavor factories, dark matter direct detection, and searches for SUSY particles in the LHC suggest that ... -
Explorations in the Space of S-Matrices
S-matrix is one of the fundamental observables of the quantum theory of relativistic particles. The quantum dynamics of relativistic particles can be abstractly understood in terms of S-matrix bypassing a Lagrangian ... -
Magnetically arrested advective accretion flows around black holes and their implications to ultraluminous X-ray sources and blazars
Black hole (BH) accretions are very powerful sources of energy in the universe. In accretion phenomena, the surrounding gas spirals down towards the central BH and forms a disc or quasi-spherical structure based on the ... -
Renormalization Group Summation at High Orders and Implications to the Determination of Some Standard Model Parameters
In perturbation theory, predictions from theories like Quantum Chromodynamics (QCD) are obtained by evaluating Feynman diagrams to high orders. Such calculations for re sults for various processes are already available ... -
Search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks in proton-proton collisions at √s= 13 TeV using CMS 2017 and 2018 data
The discovery of the Higgs boson has opened a new portal to search for Dark Matter(DM). Since DM does not interact in the CMS detector, searches rely on the missing transverse energy in association with a visible SM ...
