VBF Event Classification with Recurrent Neural Networks at ATLAS’s LHC Experiment

Applied Sciences, 2023
A novel machine learning (ML) approach based on a recurrent neural network (RNN) for event topology identification in high energy physics (HEP) is presented.

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 ...

Time-Synchronized Microwave Cavity Resonance Spectroscopy and Laser Light Extinction Measurements as a Diagnostic for Dust Particle Size and Dust Density in a Low-Pressure Radio-Frequency Driven Nanodusty Plasma

Applied Sciences, 2022
In a typical laboratory nanodusty plasma, nanometer-sized solid dust particles can be generated from the polymerization of reactive plasma species. The interplay between the plasma and the dust gives rise to behavior that is vastly different from that of

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.

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

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

Annales 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 ...

Production of K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ , Λ ( Λ ¯ $$ \overline{\Lambda} $$ ), Ξ ± , and Ω ± in jets and in the underlying event in pp and p–Pb collisions

Journal of High Energy Physics, 2023
The production of strange hadrons ( K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ , Λ, Ξ ± , and Ω ± ), baryon-to-meson ratios (Λ/ K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ , Ξ/ K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ , and Ω/ K S 0 $$ {\textrm{K}}_{\textrm{S ...

Investigating the jet activity accompanying the production at the LHC of a massive scalar particle decaying into photons

Physics Letters B, 2016
We study the jet activity that accompanies the production by gluon fusion of a new physics scalar particle decaying into photons at the LHC. In the considered scenarios, both the production and decay mechanisms are governed by loop-induced interactions ...

Beyond $$M_{t\bar{t}}$$ Mtt¯ : learning to search for a broad $$t\bar{t}$$ tt¯ resonance at the LHC

European Physical Journal C: Particles and Fields, 2020
A resonance peak in the invariant mass spectrum has been the main feature of a particle at collider experiments. However, broad resonances not exhibiting such a sharp peak are generically predicted in new physics models beyond the Standard Model. Without

Amplitude analysis and branching fraction measurement of the decay D s + $$ {\textrm{D}}_{\textrm{s}}^{+} $$ → K+ π + π − π 0

Journal 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.
