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

open access: yesEPJ 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

open access: yesPhysics 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 ...

Higgs triplet extension of GRACE

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Much theoretical effort and automatization are required to confront new physics models with experimental data for many types of particle reactions at future colliders.

Nonlinear QED and physical Lorentz invariance

open access: yesPhysical 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.

Automorphisms of Real 4 Dimensional Lie Algebras and the Invariant Characterization of Homogeneous 4-Spaces [PDF]

open access: yes, 2002
The automorphisms of all 4-dimensional, real Lie Algebras are presented in a comprehensive way. Their action on the space of $4\times 4$, real, symmetric and positive definite, matrices, defines equivalence classes which are used for the invariant ...

Conformal invariance and $2D$ statistical physics [PDF]

open access: yesBulletin of the American Mathematical Society, 2008
Summary: A number of two-dimensional models in statistical physics are conjectured to have scaling limits at criticality that are in some sense conformally invariant. In the last ten years, the rigorous understanding of such limits has increased significantly.

Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data collected by the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for resonances in events with at least one isolated lepton (e or μ) and two jets is performed using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling

Higgs boson pair production at NNLO in QCD including dimension 6 operators

open access: yesJournal of High Energy Physics, 2017
In this paper we present the computation of the Higgs boson pair production cross section, both inclusive as well as differential on the invariant mass distribution, at next-to-next-to-leading order (NNLO) in QCD including effects of new physics beyond ...
