We study the transverse spectra of hadrons in nearly central AA collisions at RHIC and LHC in a broad transverse momentum range [1]. Low-pT spectra are calculated by using boost-invariant hydrodynamics with initial energy and net-baryon densities from the EKRT [2] pQCD+saturation model. High-pT spectra are obtained from pQCD jet calculation [3] including the energy loss of the parton [4] in the...

Nonlinear energy cascades in turbulent spectra are studied in the H-1 toroidal heliac @S. M. Hamberger et al., Fusion Technol. 17, 123 ~1990!# using the spectral energy transfer estimation and the amplitude correlation technique. An inverse energy cascade of the spectral energy from the unstable range is shown to be responsible for the generation of the large-scale coherent structures dominatin...

Within the next-to-leading order (NLO) perturbative QCD (PQCD) parton model, suppression of away-side hadron spectra associated with a high pT photon due to parton energy loss is studied in high-energy heavy-ion collisions. Because of the sharp falloff of the gamma-jet spectrum in momentum imbalance pTjet-pTgamma>0 in NLO PQCD, hadron spectra at large zT=pTh/pTgamma greater than approximately 1...

A variety of statistically steady energy spectra in elastic wave turbulence have been reported in numerical simulations, experiments, and theoretical studies. Focusing on the energy levels of the system, we perform direct numerical simulations according to the Föppl-von Kármán equation, and successfully reproduce the variability of the energy spectra by changing the magnitude of external force ...

Abstract: The long-duration balloon flights of TRACER provide new measurements of the intensities and energy spectra of the arriving cosmic-ray nuclei with 5 ≤ Z ≤ 26 at high energies. In order to determine the particle composition and energy spectra at the cosmic-ray sources, changes occurring during the interstellar propagation of cosmic rays must be known. We use a simple propagation model w...
