Reaction-diffusion front crossing a local defect
Reaction-diffusion Mathematical Physics local defect
2011/7/26
Abstract: The interaction of a Zeldovich reaction-diffusion front with a localized defect is studied numerically and analytically. For the analysis, we start from conservation laws and develop simple ...
Polarization effects in $\bar N+N\to π+\ell^++\ell^-$ reaction. General analysis and numerical estimations
$\bar N+N\to π+\ell^++\ell^-$ reaction General analysis numerical estimations
2011/1/6
A general formalism is developed to calculate the cross section and the polariza-tion observables for the reaction ¯N + N ! π + ℓ+ + ℓ−. The matrix element and the observables a...

Analysis of the new Crystal Ball data on $K^-p\to\pi^0\Lambda$ reaction with beam momenta of $514\sim 750$ MeV/$c$
new Crystal Ball data on $K^-p\to\pi^0\Lambda$ reaction beam momenta $514\sim 750$ MeV/$c$
2011/1/6
The Crystal Ball Collaboration has recently reported the differential cross sections for the reaction K−p ! 0 using an incident K− beam with momenta between 514 and 750 MeV/c. We make a ...
Quantum Back-Reaction in Scale Invariant Induced Gravity
Quantum Back-Reaction Scale Invariant Induced Gravity
2010/12/20
A quartic, self-interacting potential in the induced gravity framework is known to have a pure
de Sitter attractor for the homogeneous mode. In order to obtain non-zero slow roll parameters
we there...
High-order quantum back-reaction and quantum cosmology with a positive cosmological constant
High-order quantum back-reaction quantum cosmology positive cosmological constant
2010/12/20
When quantum back-reaction by fluctuations, correlations and higher moments of a state becomes strong, semiclassical quantum mechanics resembles a dynamical system with a high-dimensional phase space....
Breakup reaction models for two- and three-cluster projectiles
Breakup reaction models for two- three-cluster projectiles
2011/1/7
Breakup reactions are one of the main tools for the study of exotic nuclei,and in particular of their continuum. In order to get valuable information from measurements.
Binomial moment equations for stochastic reaction systems
Binomial moment equations stochastic reaction systems
2010/11/17
A highly efficient formulation of moment equations for stochastic reaction networks is introduced.It is based on a set of binomial moments that capture the combinatorics of the reaction processes.The ...
Chiral Dynamics and Dubna-Mainz-Taipei Dynamical Model for Pion-Photoproduction Reaction
Chiral symmetry threshold 0 production baryon deformation
2011/1/7
We demonstrate that the Dubna-Mainz-Taipei (DMT) meson-exchange dynamical model, which starts from an effective chiral Lagrangian, for pion photoproduction pro-vides an excellent and economic framewor...
