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.

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 ...

Translationally Invariant Non-Fermi-Liquid Metals with Critical Fermi Surfaces: Solvable Models [PDF]

open access: yesPhysical Review X, 2018
Understanding the properties of metals beyond the Fermi liquid paradigm is one of the central challenges of condensed matter physics. New exactly solvable microscopic models of non-Fermi liquid metals offer new insights into many properties of these ...

Modular invariant models of lepton masses at levels 4 and 5 [PDF]

open access: yesJournal of High Energy Physics, 2019
We explore alternative descriptions of the charged lepton sector in modular invariant models of lepton masses and mixing angles. In addition to the modulus, the symmetry breaking sector of our models includes ordinary flavons.

Precise Deviations for Disk Counting Statistics of Invariant Determinantal Processes [PDF]

open access: yes, 2020
We consider two-dimensional determinantal processes which are rotation-invariant and study the fluctuations of the number of points in disks. Based on the theory of mod-phi convergence, we obtain Berry-Esseen as well as precise moderate to large ...

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 ...

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

New physics contributions to moments of inclusive b → c semileptonic decays

open access: yesJournal of High Energy Physics, 2023
Inclusive semileptonic B → X c ℓ ν ¯ ℓ $$ {X}_c\ell {\overline{\nu}}_{\ell } $$ decays, where ℓ = μ, e, are by now standard candles in the determination of the CKM element |V cb |. These determinations rely on the heavy-quark expansion and use moments of

Searches for new physics using the tt¯ invariant mass distribution in pp collisions at √s=8 TeV.

open access: yesPhysical Review Letters, 2013
Searches for anomalous top quark-antiquark production are presented, based on pp collisions at √s=8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb(-1), were collected with the CMS detector at the LHC.
