Physics Informed Neural Networks Applied to the Description of Wave-Particle Resonance in Kinetic Simulations of Fusion Plasmas [PDF]

open access: green, 2023
The Vlasov-Poisson system is employed in its reduced form version (1D1V) as a test bed for the applicability of Physics Informed Neural Network (PINN) to the wave-particle resonance. Two examples are explored: the Landau damping and the bump-on-tail instability.

L3 physics at the Z resonance and a search for the Higgs particle [PDF]

open access: bronze, 1997
This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory. Electroweak interactions were studied using the L3 Detector on the Large Electron-Positron Collider (LEP) at the European Center for Nuclear Study (CERN).

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

open access: yesPhysical Review D, 2000
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 ...

Rho-meson resonance broadening in QCD at finite temperature [PDF]

open access: yesPhysical Review D, 2012
Thermal Finite Energy QCD sum rules for the vector current correlator are used to study quark-gluon deconfinement. Assuming $ $-meson saturation of the correlator in the hadronic sector, and the Operator Product Expansion in QCD, we obtain the temperature behavior of the resonance parameters (coupling, mass, and width), and of the leading vacuum ...

Searches for high mass resonances with the CMS detector

open access: yesEPJ Web of Conferences, 2012
New heavy resonances are predicted by many extensions of the standard model of particle physics. Recent results for high mass resonance searches with the Compact Muon Solenoid detector, in the diphoton, dilepton, dijet and tt¯ $tar t$ channels, are ...

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 ...

The effect of composite resonances on Higgs decay into two photons [PDF]

open access: yesThe European Physical Journal C, 2014
In scenarios of strongly coupled electroweak symmetry breaking, heavy composite particles of different spin and parity may arise and cause observable effects on signals that appear at loop levels. The recently observed process of Higgs to $ $ at the LHC is one of such signals. We study the new constraints that are imposed on composite models from $H\

New narrow N*(1685) resonance: Review of observations

open access: yesEPJ Web of Conferences, 2014
The recent Review of Particle Physics [1] includes a new narrow N*(1685) resonance. Its properties, the narrow width (Γ < 25 MeV) and the strong photoexcitation on the neutron, are unusual.

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.
