We are presenting here the new formulae for Bose-Einstein correlations (BEC) which contain effects of final state interactions (FSI) of both strong (in s-wave) and electromagnetic origin. We demonstrate the importance of FSI in BEC by analysing data for e + e − annihilation and for heavy collisions. The inclusion of FSI results in the practical elimination… (More)

The evolution of charged-particle production in collisions of heavy ions at relativistic energies is investigated as function of centrality in a nonequilibrium-statistical framework. Precise agreement with recent d + Au and Au + Au data at √ s N N = 200 GeV is found in a Relativistic Diffusion Model with three sources for particle production. Only the… (More)

To explain η-distributions at RHIC energies we consider the Ornstein-Uhlenbeck process. To account for hadrons produced in the central region, we assume existence of third source located there (y ≈ 0) in addition to two sources located at the beam and target rapidities (±ymax = ± ln [ √ sNN /mN ]). This results in better χ 2 /n.d.f. than those for only two… (More)

In 1+1 dimensional hydrodynamics originally proposed by Landau, we derive a new potential and distribution function including Heaviside function and investigate its mathematical and physical properties. Using the original distribution derived by Landau, a distribution function found by Srivastava et al., our distribution function, and the Gaussian… (More)

The recent data for Bose-Einstein Correlations (BEC) of three-charged particles obtained by NA44 Collaboration have been analysed using theoretical formula with Coulomb wave functions. It has been recently proposed by Alt et al. It turns out that there are discrepancies between these data and the respective theoretical values. To resolve this problem we… (More)

We have systematically estimated the possible temperatures obtained from an analysis of recent data on pt distributions observed at RHIC experiments. Using the fact that observed pt distributions cannot be described by the original Hagedorn formula in the whole range of transverse momenta (in particular above 6 GeV/c), we propose a modified Hagedorn formula… (More)

A compact model of GaN HEMT is developed, which solves the Poisson equations explicitly. The model includes all possible charges induced within the device including the trap density. It is verified that the model can reproduce all 2D-device simulation results accurately. In particular, the operation frequency dependence of the current collapse can also be… (More)

Analyses of dN ch /dη and dN ch /dy distributions of BRAHMS Collaboration by means of the Ornstein-Uhlenbeck process Abstract Interesting data on dN ch /dη in Au-Au collisions (η = − ln tan(θ/2)) with the centrality cuts have been reported by BRAHMS Collaboration. Using the total multiplicity N ch = (dN ch /dη)dη, we find that there are scaling phenomena… (More)
