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

Searches for high mass resonances with the CMS detector
EPJ 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 ...

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

HF doppler sounder measurements of the ionospheric signatures of small scale ULF waves [PDF]
Annales Geophysicae, 2005 An HF Doppler sounder, DOPE (DOppler Pulsation Experiment) with three azimuthally-separated propagation paths is used to provide the first statistical examination of small scale-sized, high m waves where a direct measurement of the azimuthal ...

Modelling substorm chorus events in terms of dispersive azimuthal drift [PDF]
Annales Geophysicae, 2004 The Substorm Chorus Event (SCE) is a radio phenomenon observed on the ground after the onset of the substorm expansion phase. It consists of a band of VLF chorus with rising upper and lower cutoff frequencies.

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

ULF waves with drift resonance and drift-bounce resonance energy sources as observed in artificially-induced HF radar backscatter [PDF]
Annales Geophysicae, 2001 HF radar backscatter which has been artificially-induced by a high power RF facility such as the EISCAT heater at Tromsø has been demonstrated to provide ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data
