HF doppler sounder measurements of the ionospheric signatures of small scale ULF waves [PDF]

open access: yesAnnales 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]

open access: yesAnnales 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.

ULF waves with drift resonance and drift-bounce resonance energy sources as observed in artificially-induced HF radar backscatter [PDF]

open access: yesAnnales 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

Fate of Multiparticle Resonances: From $Q$-Balls to $^3$He Droplets [PDF]

open access: yesPhys. Rev. A 106, L050801 (2022), 2021
We consider a system of $N$ nonrelativistic particles which form a near-threshold resonance. Assuming no subset of these particles can form a bound state, the resonance can only decay through an "explosion" into $N$ particles. We show that the decay width of the resonance scales as $E^{\Delta-5/2}$ in the limit when the energy $E$ of the resonance goes

Role of wave-particle resonance in turbulent transport in toroidal plasmas [PDF]

open access: yes, 2021
Wave-particle interaction in toroidal plasmas is an essential transport mechanism in drift wave instability-driven microturbulence. In tokamkas, different wave-particle resonance conditions have been found important for the energy and particle transport of multiple species in various drift wave turbulences.

Pure spin-3/2 propagator for use in particle and nuclear physics [PDF]

open access: yes, 2017
We propose the use of a pure spin-3/2 propagator in the (3/2,0)⊕(0,3/2) representation in particle and nuclear physics. To formulate the propagator in a covariant form we use the antisymmetric tensor spinor representation and we consider the Δ resonance ...

Evidence for acceleration of outer zone electrons to relativistic energies by whistler mode chorus [PDF]

open access: yesAnnales Geophysicae, 2002
We use plasma wave and electron data from the Combined Release and Radiation Effects Satellite (CRRES) to investigate the viability of a local stochastic electron acceleration mechanism to relativistic energies driven by gyroresonant interactions ...

Attosecond timing of electron emission from a molecular shape resonance [PDF]

open access: yesScience Advances, 2019
In a vibrating N2 molecule, a mere 2% change in bond length can delay electron emission by 100 attoseconds near a shape resonance. Shape resonances in physics and chemistry arise from the spatial confinement of a particle by a potential barrier.

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.

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 ...
