How does the S11 N^*(890) state emerge from a naive K-matrix fit?
《Communications in Theoretical Physics》2020年第10期92-97,共6页Yao Ma Wen-Qi Niu Yu-Fei Wang Han-Qing Zheng 
supported in part by the National Nature Science Foundations of China under contract numbers 11975028 and 10925522;by the Sino-German CRC 110(Grant No.TRR110)。
We give a pedagogical analysis on K-matrix models describing theπN scattering amplitude,in S11 channel at low energies.We show how the correct use of analyticity in the s-channel and crossing symmetry in t-and u-chan...

Effect of fracture-skin on virus transport in fractured porous media
《Geoscience Frontiers》2012年第6期893-900,共8页N.Natarajan G.Suresh Kumar 
A numerical model is developed for describing the transport of virus in a fracture-matrix coupled system with fracture-skin. An advective dispersive virus transport equation, including first- order sorption and inacti...

Bonn-Gatchina partial wave analysis
《Chinese Physics C》2009年第12期1085-1092,共8页A. Sarantsev 
The present status of the Bonn-Gatchina partial wave analysis of the photoproduction and pion induced data is presented. An observation of signals which can be associated with new baryon resonances and possible interp...

Role of t-channel meson exchanges in S-wave πN and KN scatterings
《Chinese Physics C》2008年第8期629-633,共5页吴锋泉 张印杰 邹冰松 
National Natural Science Foundation of China (10435080, 10521003);Chinese Academy of Sciences (KJCX3-SYW-N2)
The low-energy S-wave πN and KN scatterings are studied by using the K-matrix approach within the meson exchange framework. The t-channel meson exchanges, especially ρ and σ exchanges, are found to play a very impo...

Solution Transformations and Their Effects on the Systems with Open Boundary Conditions
《Communications in Theoretical Physics》2002年第4期397-404,共8页JUGuo－Xing ZhaoXian－Lin 
Natural Science Foundation of Science and Technology Committee of Henan Proviuce，河南师范大学校科研和教改项目
The solution transformations and properties of the -matrices for two-component systems under these transformations are analyzed in details. Not all transformed -matrices can be put into the Skalyanin's formalism. For ...

BASIC PROPERTIES OF K-SPACES
《Systems Science and Mathematical Sciences》1992年第3期233-238,共6页CHARLES Swartz 
Every complete metric linear space is a K-space.A non-completenormed space can be a K-space.And non-metrizable K-spaces exist.A series ofbasic results on complete metric linear spaces Can be generalized to K-spaces.Fo...
