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...
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...

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 $...
Attempt-time Monte Carlo: an alternative for simulation of stochastic jump processes with time-dependent transition rates
Attempt-time Monte Carlo simulation of stochastic jump processes time-dependent transition rates
2010/11/24
cWe present a new method for simulating Markovian jump processes with time-dependent tran-
sitions rates, which avoids the transformation of random numbers by inverting time integrals over the rates....

2011/1/14
We illustrate the stochastic method for solving the Schwinger-Dyson equations in large-N quantum field theories described in ArXiv:1009.4033 on the example of the Gross-Witten unitary matrix model.

Parton Distribution Function sensitivity studies electroweak processes
2011/1/4
We describe parton density function sensitivity studies, using muon final states produced through the Drell-Yan process viaW, Z or g down to a Q2 of 10 GeV2. This makes use of LHCb’s unique ability t...
Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes
Effective Field Theory High-Precision Calculations of Nuclear Electroweak Processes
2011/1/7
High-precision calculations of electroweak processes in light nuclei are of great importance
for multiple reasons. Gerry Brown together with Dan-Olof Riska published in 1972 a famous calculation on r...

Exclusive Processes Antiprotons: Opportunities QCD Studies
2011/1/10
The detection of exclusive processes induced by antiproton beams in the GeV range at PANDA(FAIR) opens possibilities for testing QCD predictions on the nucleon structure. In particular, the measuremen...
Our starting point is a particular `canvas' aimed to `draw' theories of physics,which has symmetric monoidal categories as its mathematical backbone. In this paper we consider the conceptual foundatio...

2010/4/27
We consider stochastic point processes generating time series exhibiting power laws of spectrum and distribution density (Phys. Rev. E 71, 051105 (2005)) and apply them for modeling the trading activi...
