Prompt and nonprompt ψ(2S) production in pPb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 8.16 TeV

open access: yesJournal of High Energy Physics
The production of ψ(2S) mesons in proton-lead collisions at a centre-of-mass energy per nucleon pair of s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 8.16 TeV is studied with the LHCb detector using data corresponding to an integrated luminosity of 34 nb −1.

Resonance production in high energy collisions from small to big systems

open access: yesEPJ Web of Conferences, 2018
The aim of this paper is to understand resonance production (and more generally particle production) for different collision systems, namely proton-proton (pp), proton-nucleus (pA), and nucleus-nucleus (AA) scattering at the LHC.

Measurement of the B ± production cross-section in pp collisions at s=7 $$ \sqrt{s}=7 $$ and 13 TeV

open access: yesJournal of High Energy Physics, 2017
The production of B ± mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B ± → J/ψ K ± decays and data samples corresponding to 1.0 fb−1 and 0.3 fb−1, respectively.

Universe Reheating after Inflation

open access: yes, 1994
We study the problem of scalar particle production after inflation by a rapidly oscillating inflaton field. We use the framework of the chaotic inflation scenario with quartic and quadratic inflaton potentials.

Kaon femtoscopy of Pb-Pb and pp collisions at the LHC with the ALICE experiment

open access: yes, 2013
We report on the results of femtoscopic analyses of Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV and pp collisions at $\sqrt{s}$= 7 TeV with identical charged and neutral kaons.

Search for Narrow-Width ttbar Resonances in ppbar Collisions at center of mass energy = 1.8 TeV

open access: yes, 2003
We present a preliminary result on a search for narrow-width resonances that decay into ttbar pairs using 130 pb^{-1} of lepton plus jets data in ppbar collisions at center of mass energy = 1.8 TeV. No significant deviation from Standard Model prediction

Resonant production of heavy particles during inflation and its gravitational wave signature

open access: yes
We show that a quadratic $U(1)$-breaking term, together with an effective chemical potential induced by a dimension five derivative coupling between the inflaton and the $U(1)$ current, can drive efficient particle production during inflation even when the $U(1)$ field is heavier than the Hubble scale.

Amplifying nonresonant production of dark sector particles in scattering dominance regime

open access: yesPhysical Review D
We investigate the enhancement of dark sector particle production within the scattering dominant regime. These particles typically exhibit a slight mixing with Standard Model particles through various portals, allowing for their generation through in-medium oscillation from Standard Model particle sources.

Resonance Production in RHIC Collisions

open access: yes, 2006
Results of resonance particle production measured at RHIC in $\sqrt{s_{\rm NN}} = $ 200 GeV Au+Au collisions are compared to measurements in p+p and d+Au collisions in order to verify the existence of an extended hardronically interacting medium.
