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.

Production of cascade hypernuclei via the (K-,K+) reaction within a quark-meson coupling model

open access: yes, 2012
We study the production of bound cascade hypernuclei via the (K-,K+) reaction on 12C and 28Si targets within a covariant effective Lagrangian model, employing the cascade bound state spinors derived from the latest quark-meson coupling model as well as ...

Constraints on resonant particle production during inflation from the matter and CMB power spectra

open access: yesPhysical Review D, 2004
We analyze the limits on resonant particle production during inflation based upon the power spectrum of fluctuations in matter and the cosmic microwave background. We show that such a model is consistent with features observed in the matter power spectrum deduced from galaxy surveys and damped Lyman-alpha systems at high redshift.

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 ...

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 ...

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.

A stopped Delta-Matter Source in Heavy Ion Collisions at 10 GeV/n

open access: yes, 1994
We predict the formation of highly dense baryon-rich resonance matter in Au+Au collisions at AGS energies. The final pion yields show observable signs for resonance matter.
