Four-Quark Effective Operators at Hadron Colliders [PDF]
, 2014 The robustness of translating effective operator constraints to BSM theories crucially depends on the mass and coupling of BSM particles. This is especially relevant for hadron colliders where the partonic centre of mass energy is around the typical ...

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We visited mass spectra and decay constants of pseudoscalar and vector heavy‐light mesons (B, Bs, D, and DS) in the framework of QCD sum rule and quark model. The harmonic oscillator wave function was used in quark model while a simple interpolating current was used in QCD sum rule calculation.

A guide to diagnosing colored resonances at hadron colliders
Journal of High Energy Physics, 2023 We present a comprehensive study on how to distinguish the properties of heavy dijet resonances at hadron colliders. A variety of spins, chiral couplings, charges, and QCD color representations are considered.

Exclusion Limits on a Scalar Decaying to Photons and Distinguishing Its Production Mechanisms
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 LHC run‐II has a great potential to search for new resonances in the diphoton channel. Latest 13 TeV data already put stringent limits on the cross sections in the diphoton channel assuming the resonance is produced through the gluon‐gluon fusion. Many beyond the Standard Model (SM) theories predict TeV‐scale scalars, which copiously decay to diphotons.

Higgs decay into four charged leptons in the presence of dimension-six operators
, 2018 We study the indirect effects of New Physics in the Higgs decay into four charged leptons, using an Effective Field Theory (EFT) approach to Higgs interactions.

LHC Probes of TeV‐Scale Scalars in SO(10) Grand Unification
Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017 We investigate the possibility of TeV‐scale scalars as low energy remnants arising in the nonsupersymmetric SO(10) grand unification framework where the field content is minimal. We consider a scenario where the SO(10) gauge symmetry is broken into the gauge symmetry of the Standard Model (SM) through multiple stages of symmetry breaking, and a colored

Electroweak spin-1 resonances in Composite Higgs models
Journal of High Energy PhysicsComposite Higgs models predict the existence of various bound states. Among these are spin-1 resonances. We investigate models containing SU(2) L × SU(2) R as part of the unbroken subgroup in the new strong sector. These models predict that there are two

A simple symmetry as a guide toward new physics beyond the Standard Model [PDF]
, 2013 There exists one experimental result that cannot be explained by the Standard Model (SM), the current theoretical framework for particle physics: non-zero masses for the neutrinos (elementary particles travelling close to light speed, electrically ...

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.
