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 ...

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.

Anomalous diffusion of pions at RHIC [PDF]

open access: yes, 2007
After pointing out the difference between normal and anomalous diffusion, we consider a hadron resonance cascade (HRC) model simulation for particle emission at RHIC and point out, that rescattering in an expanding hadron resonance gas leads to a heavy ...

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

Cyclotron resonant interactions in cosmic particle accelerators [PDF]

open access: yesSpace Science Reviews, 173, 623-640, 2012, 2012
A review is given for cyclotron resonant interactions in space plasmas. After giving a simple formulation for the test particle approach, illustrative examples for resonant interactions are given. It is shown that for obliquely propagating whistler waves, not only fundamental cyclotron resonance, but also other resonances, such as transit-time ...

Fast resonance decays in nuclear collisions [PDF]

open access: yesNuclear Physics, 2018
In the context of ultra-relativistic nuclear collisions, we present a fast method for calculating the final particle spectra after the direct decay of resonances from a Cooper–Frye integral over the freeze-out surface.

Probing the Phase Boundary between Hadronic Matter and the Quark-Gluon-Plasma in Relativistic Heavy Ion Collisions [PDF]

open access: yes, 1996
We discuss recent data on particle production with emphasis on the degree of thermal and chemical equilibration achieved. The data are interpreted in terms of a resonance gas model.

Gauge-invariant description of the Higgs resonance and its phenomenological implications [PDF]

open access: yesPhysical Review D, 2020
We investigate the phenomenological consequences of a strict gauge-invariant formulation of the Higgs particle. This requires a description of the observable scalar particle in terms of a bound state structure.
