Quasi-particles and their absence in photoemission spectroscopy [PDF]

open access: yes, 2002
The elucidation of Landau Fermi liquid quasi-particles and their absence in strongly correlated electron systems lies at the heart of modern research on the quantum mechanics of electrons in condensed matter.

Anomalous diffusion of pions at RHIC [PDF]

open access: yes, 2007
After pointing out the difference between normal and anomalous diffusion, we consider a hadron resonance cascade (HRC) model simulation for particle emission at RHIC and point out, that rescattering in an expanding hadron resonance gas leads to a heavy ...

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

open access: yesPhysics 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 ...

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

open access: yes, 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).

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

open access: yes, 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.

Fermionic statistics suppresses Fano resonances [PDF]

open access: yes, 2014
Fano resonances and bound states with energy in the continuum are ubiquitous phenomena in different areas of physics. Observations, however, have been limited so far to single-particle processes.

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

open access: yesEuropean 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 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.

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 ...
