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 ...

Fermionic statistics suppresses Fano resonances [PDF]

open access: yes, 2014
Fano resonances and bound states with energy in the continuum are ubiquitous phenomena in different areas of physics. Observations, however, have been limited so far to single-particle processes.

Beyond $$M_{t\bar{t}}$$ Mtt¯ : learning to search for a broad $$t\bar{t}$$ tt¯ resonance at the LHC

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A resonance peak in the invariant mass spectrum has been the main feature of a particle at collider experiments. However, broad resonances not exhibiting such a sharp peak are generically predicted in new physics models beyond the Standard Model. Without

Amplitude analysis of the D + → π − π + π + decay and measurement of the π − π + S-wave amplitude

open access: yesJournal of High Energy Physics, 2023
An amplitude analysis of the D + → π − π + π + decay is performed with a sample corresponding to 1.5 fb −1 of integrated luminosity of pp collisions at a centre-of-mass energy s $$ \sqrt{s} $$ = 8 TeV collected by the LHCb detector in 2012.

Amplitude analysis and branching fraction measurement of the decay D s + $$ {\textrm{D}}_{\textrm{s}}^{+} $$ → K+ π + π − π 0

open access: yesJournal of High Energy Physics, 2022
The singly Cabibbo-suppressed decay D s + $$ {D}_s^{+} $$ → K + π + π − π 0 is observed by using a data set corresponding to an integrated luminosity of 6.32 fb −1 recorded by the BESIII detector at the centre-of-mass energies between 4.178 and 4.226 GeV.

Effect of the Generalized Uncertainty Principle on Post-Inflation Preheating [PDF]

open access: yes, 2011
We examine effects of the Generalized Uncertainty Principle, predicted by various theories of quantum gravity to replace the Heisenberg's uncertainty principle near the Planck scale, on post inflation preheating in cosmology, and show that it can predict

Rho-meson resonance broadening in QCD at finite temperature [PDF]

open access: yesPhysical Review D, 2012
Thermal Finite Energy QCD sum rules for the vector current correlator are used to study quark-gluon deconfinement. Assuming $ $-meson saturation of the correlator in the hadronic sector, and the Operator Product Expansion in QCD, we obtain the temperature behavior of the resonance parameters (coupling, mass, and width), and of the leading vacuum ...

Amplitude analysis of the D s + $$ {D}_s^{+} $$ → π − π + π + decay

open access: yesJournal of High Energy Physics, 2023
A Dalitz plot analysis of the D s + $$ {D}_s^{+} $$ → π − π + π + decay is presented. The analysis is based on proton-proton collision data recorded by the LHCb experiment at a centre-of-mass energy of 8 TeV and corresponding to an integrated luminosity ...

The effect of composite resonances on Higgs decay into two photons [PDF]

open access: yesThe European Physical Journal C, 2014
In scenarios of strongly coupled electroweak symmetry breaking, heavy composite particles of different spin and parity may arise and cause observable effects on signals that appear at loop levels. The recently observed process of Higgs to $ $ at the LHC is one of such signals. We study the new constraints that are imposed on composite models from $H\
