An analytical approach to the field amplification and particle production by parametric resonance during inflation and reheating [PDF]

Physics of the Dark Universe 26, 100373 (2019), 2018
Field amplification and particle production due to parametric resonance are highly nontrivial predictions of quantum fields that couple to an oscillating source during inflation and reheating. Understanding this two effects is crucial for the connection between the resonance phenomenon and precise observational data.

Particles Production in Neutron Stars by Means of the Parametric Resonance Mechanism [PDF]

arXiv, 2008
Using a Lagrangean toy model the coupling of a negative pion superconducting field and the electromagnetic field of the star is analyzed. A numerical study of particles produced in the neutron star medium by means of the well-known parametric resonance phenomenon is performed.

Probing Planckian physics: resonant production of particles during inflation and features in the primordial power spectrum [PDF]

Phys.Rev. D62 (2000) 043508, 1999
The phenomenon of resonant production of particles {\it after} inflation has received much attention in the past few years. In a new application of resonant production of particles, we consider the effect of a resonance {\em during} inflation. We show that if the inflaton is coupled to a massive particle, resonant production of the particle during ...

Resonance enhancement of particle production during reheating [PDF]

Classical and Quantum Gravity, 2001
We found a consistent equation of reheating after inflation which shows that for small quantum fluctuations the frequencies of resonance are slighted different from the standard ones.

K*0(892) and phi(1020) resonance production at RHIC [PDF]

, 2015
The measurement of resonance production in ultrarelativistic heavy-ion collisions provides a glimpse of the hadronic medium properties and its evolution at different stages. Resonances decaying into hadrons are used to estimate the time span and hadronic interaction cross section in the hadronic phase between chemical and kinetic freeze-out ...

Multi-step production of a diphoton resonance [PDF]

, 2016
Among the questions that would be raised by the observation of a new resonance at the LHC, particularly pressing are those concerning the production mechanism: What is the initial state? Is the resonance produced independently or in association with other particles?

Resonance production in high energy collisions from small to big systems [PDF]

EPJ 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.

Strange Resonance Production: Probing Chemical and Thermal Freeze-out in Relativistic Heavy Ion Collisions [PDF]

Phys.Lett. B530 (2002) 81-87, 2002
The production and the observability of $\Lambda(1520)$, $K^0(892)$ $\Phi$ and $\Delta(1232)$ hadron resonances in central Pb+Pb collisions at 160 AGeV is addressed. The rescattering probabilities of the resonance decay products in the systems evolution are studied.

Final state interaction in the production of heavy unstable particles [PDF]

Nucl.Phys. B471 (1996) 90-120, 1995
We make an attempt to discuss in detail the effects originating from the final state interaction in the processes involving production of unstable elementary particles and their subsequent decay. Two complementary scenarios are considered: the single resonance production and the production of two resonances. We argue that part of the corrections due to

Hadronic Resonance Production with ALICE Experiment at LHC [PDF]

arXiv, 2013
The production of resonances in heavy-ion collisions is expected to be sensitive to the properties of strongly interacting matter created in such collisions. We report on the measurements of $\phi$ and $K^{*0}$ resonances in Pb-Pb collisions at $\sqrt{s_{NN}} $ = 2.76 TeV.
