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.

Measurement of Λ (1520) production in pp collisions at √s=7TeV and p–Pb collisions at √sNN=5.02TeV [PDF]

open access: yes, 2020
The production of the Λ (1520) baryonic resonance has been measured at midrapidity in inelastic pp collisions at s=7TeV and in p–Pb collisions at sNN=5.02TeV for non-single diffractive events and in multiplicity classes.

Multiplicity-dependent production of Σ(1385) ± and Ξ(1530)0 in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
The production yields of the Σ(1385) ± and Ξ(1530)0 resonances are measured in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with ALICE. The measurements are performed as a function of the charged-particle multiplicity ⟨dN ch /dη⟩, which is related to the ...

Event-by-Event Fluctuations of Particle Ratios in Heavy-Ion Collisions

open access: yes, 2006
We study event-by-event dynamical fluctuations of various particle ratios at different energies. We assume that particle production in final state is due to chemical equilibrium processes.

Light-flavor particle production in high-multiplicity pp collisions at s $$ \sqrt{\textrm{s}} $$ = 13 TeV as a function of transverse spherocity

open access: yesJournal of High Energy Physics
Results on the transverse spherocity dependence of light-flavor particle production (π, K, p, ϕ, K*0, K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ , Λ, Ξ) at midrapidity in high-multiplicity pp collisions at s $$ \sqrt{s} $$ = 13 TeV were obtained with the ...

Non-Linear Resonance in Relativistic Preheating

open access: yes, 2014
Inflation in the early Universe can be followed by a brief period of preheating, resulting in rapid and non-equilibrium particle production through the dynamics of parametric resonance.
