Weyl-invariant Einstein-Cartan gravity: unifying the strong CP and hierarchy puzzles [PDF]

Journal of High Energy Physics
We show that the minimal Weyl-invariant Einstein-Cartan gravity in combination with the Standard Model of particle physics contains just one extra scalar degree of freedom (in addition to the graviton and the Standard Model fields) with the properties of

Nonlinear QED and physical Lorentz invariance

Physical Review D, 2006
The spontaneous breakdown of 4-dimensional Lorentz invariance in the framework of QED with the nonlinear vector potential constraint A_ ^{2}=M^{2}(where M is a proposed scale of the Lorentz violation) is shown to manifest itself only as some noncovariant gauge choice in the otherwise gauge invariant (and Lorentz invariant) electromagnetic theory.

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.

emcee v3: A Python ensemble sampling toolkit for affine-invariant MCMC [PDF]

Journal of Open Source Software, 2019
emcee is a Python library implementing a class of affine-invariant ensemble samplers for Markov chain Monte Carlo (MCMC). This package has been widely applied to probabilistic modeling problems in astrophysics where it was originally published, with some

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.

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 ...

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.
