Chiral Symmetry and Electroweak pi,K, n Processes
Chiral perturbation theory the low energy electroweak symmetry goldstone boson
2014/12/23
Recently the development of chiral perturbation theory has allowed the generation of rigorous low-energy theorems for various hadronic processes based only on the chiral invariance of the underlying Q...
Quasiclassical approach to high-energy QED processes in strong laser and atomic fields
Quasiclassical high-energy QED processes strong laser atomic fields Atomic Physics
2012/4/20
An approach, based on the use of the quasiclassical Green's function, is developed for investigating high-energy quantum electrodynamical processes in combined strong laser and atomic fields. Employin...
On the Determination of \bar{d}/\bar{u} Ratios from Proton-Proton and Proton-Deuteron Drell-Yan Processes
Proton-Proton Proton-Deuteron Drell-Yan Processes
2011/7/21
By using the convolution formula derived within the framework of relativistic quantum mechanics, we have examined the Fermi Motion effects on the ratios R_{pd/pp}= sigma^{pd}/(2 sigma^{pp}) between th...
Leading twist nuclear shadowing phenomena in hard processes with nuclei
shadowing phenomena hard processes nuclei
2011/7/21
We present and discuss the theory and phenomenology of the leading twist theory of nuclear shadowing which is based on the combination of the generalization of Gribov-Glauber theory, QCD factorization...
Role of quark-interchange processes in evolution of mesonic matter
quark-interchange processes master rate equations mesonic matter
2011/7/20
We divide the cross section for a meson-meson reaction into three parts. The first part is for the quark-interchange process, the second for quark-antiquark annihilation processes and the third for re...
Femtosecond pulses in a dense two-level medium: Spectral transformations, transient processes, and collisional dynamics
Femtosecond pulses dense two-level medium Spectral transformations transient processes collisional dynamics
2011/8/5
Abstract: Propagation of ultrashort optical pulses in a dense resonant medium is considered in the semiclassical limit. In our analysis, we place emphasis on several main points. First, we study trans...
Thermal processes generated in quark-gluon plasma by yoctosecond laser pulses
QGP thermal waves yoctosecond pulses
2011/8/2
Abstract: In this paper the thermal processes generated by yoctosecond (10-24 s) laser pulses in QGP are investigated. Considering that the relaxation time in QGP is of the order of 1 ys it is shown t...
Markov property of determinantal processes with extended sine, Airy, and Bessel kernels
Determinantal processes Correlation kernels Random matrix theory Infinite particle systems Markov property
2011/7/28
Abstract: When the number of particles is finite, the noncolliding Brownian motion (the Dyson model) and the noncolliding squared Bessel process are determinantal diffusion processes for any determini...

2011/7/27
Abstract: Consider an N-dimensional Markov chain obtained from N one-dimensional random walks by Doob h-transform with the q-Vandermonde determinant. We prove that as N becomes large, these Markov cha...
Abstract: A discrete quantum process is defined as a sequence of local states $\rho_t$, $t=0,1,2,...$, satisfying certain conditions on an $L_2$ Hilbert space $H$. If $\rho =\lim\rho_t$ exists, then $...
