Top Quark Pairs at High Invariant Mass - A Model-Independent Discriminator of New Physics at the LHC [PDF]

, 2006
We study top quark pair production to probe new physics at the LHC. We propose reconstruction methods for $t\bar{t}$ semileptonic events and use them to reconstruct the $t\bar{t}$ invariant mass. The angular distribution of top quarks in their c.m. frame

Searches for new physics in collision events using a statistical technique for anomaly detection

SciPost Physics Proceedings, 2022
This paper discusses a statistical anomaly-detection method for model-independent searches for new physics in collision events produced at the Large Hadron Collider (LHC).

Predictions from Heavy New Physics Interpretation of the Top Forward-Backward Asymmetry [PDF]

, 2012
We derive generic predictions at hadron colliders from the large forward-backward asymmetry observed at the Tevatron, assuming the latter arises from heavy new physics beyond the Standard Model.

Neural Network-Based Intuitive Physics for Non-Inertial Reference Frames

IEEE Access, 2021
Classical mechanics offers us reliable means to predict various physical quantities, but it is difficult to derive the precise dynamic equations underlying most phenomena and obtain physical quantities in real-world situations.

On interpolating anomalous dimension of twist-two operators with general spins

Journal of High Energy Physics, 2019
We study non-perturbative interpolating functions to probe the physics of anomalous dimensions associated with twist-two operators in N = 4 $$ \mathcal{N}=4 $$ SYM of finite and infinite spin.

Unitarity Triangles and the Search for New Physics [PDF]

, 2002
Assuming that the Kobayashi-Maskawa mechanism gives the dominant contribution to CP violation at low energies, we propose a novel way of testing the flavour sector of the Standard Model which has the potencial for discovering New Physics.

Search for new neutral gauge bosons with the CMS Experiment at the LHC

EPJ Web of Conferences, 2018
A search for narrow resonances in dimuon invariant mass spectra has been performed using 13 fb-1 data obtained in 2016 from proton-proton collisions at √s = 13 TeV with the CMS experiment at the LHC. No evidence for physics beyond standard model is found.

Investigating the jet activity accompanying the production at the LHC of a massive scalar particle decaying into photons

Physics Letters B, 2016
We study the jet activity that accompanies the production by gluon fusion of a new physics scalar particle decaying into photons at the LHC. In the considered scenarios, both the production and decay mechanisms are governed by loop-induced interactions ...

CP violation in three-body B decays: a model ansatz

Journal of High Energy Physics, 2020
The mechanism of CP violation remains one of the puzzles in particle physics. Key to understanding this phenomenon are nonleptonic B decays, especially multibody decays which exhibit large CP asymmetries in various regions of phase space.

A topological invariant of RG flows in 2D integrable quantum field theories [PDF]

, 1999
We construct a topological invariant of the renormalization group trajectories of a large class of 2D quantum integrable models, described by the thermodynamic Bethe ansatz approach.
