Electromagnetic KY production from the proton in a Regge-plus-resonance approach [PDF]

open access: yes, 2007
A Regge-plus-resonance (RPR) description of the p(\gamma,K)Y and p(e,e'K)Y processes (Y = \Lambda, \Sigma^{0,+}) is presented. The proposed reaction amplitude consists of Regge-trajectory exchanges in the t channel, supplemented with a limited selection ...

Neutrinos from Cosmic Accelerators including Magnetic Field and Flavor Effects

open access: yesAdvances in High Energy Physics, 2012
We review the particle physics ingredients affecting the normalization, shape, and flavor composition of astrophysical neutrinos fluxes, such as different production modes, magnetic field effects on the secondaries (muons, pions, and kaons), and flavor ...

Neutrino Spin Transitions and the Violation of the Equivalence Principle [PDF]

open access: yes, 1996
The violation of the equivalence principle (VEP) causing neutrino oscillations is of current interest. We study here the possibility of not only flavor oscillation but spin flavor oscillation of ultra high energy ($ \sim$ 1 PeV) neutrinos emanating from ...

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

open access: yesJournal 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 ...

Nonlinear interaction between particles and ultralow frequency waves

open access: yes地球与行星物理论评, 2022
One of the most important questions in space physics is how the energy of the solar wind is transmitted to energetic particles in the Earth's magnetosphere, part of which is in the form of ultra-low-frequency (ULF) electromagnetic waves in the mHz ...

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 ...

Cosmological magnetic fields by parametric resonance? [PDF]

open access: yes, 2000
We investigate the possibility that electromagnetic fluctuations are amplified in expanding universe by parametric resonance, during the oscillatory regime of a scalar field to which they are coupled.

Probing a leptophobic top-colour model with cross section measurements and precise signal and background predictions: A case study

open access: yesSciPost Physics Core, 2023
The sensitivity of particle-level fiducial cross section measurements from ATLAS, CMS and LHCb to a leptophobic top-colour model is studied. The model has previously been the subject of resonance searches.

Effect of the Generalized Uncertainty Principle on Post-Inflation Preheating [PDF]

open access: yes, 2011
We examine effects of the Generalized Uncertainty Principle, predicted by various theories of quantum gravity to replace the Heisenberg's uncertainty principle near the Planck scale, on post inflation preheating in cosmology, and show that it can predict
