Chiral Lagrangian with higher resonances and flavour SU(3) SU(3) breaking

A chiral Lagrangian with $SU(3)$ breaking and higher resonances is proposed. In this model, the $SU(3)$ breaking structure in vector-pseudoscalar sector is realized with the decay constants of pseudoscalar mesons and the masses of vector mesons used as inputs. We examine whether the resulting $SU(3)$ breaking effect in the charge radii of pseudoscalar mesons is consistent with the experimental facts.Comment: 29 pages, REVTEX(ver.3), DPNU-93-3

Location Choice of Multinational Enterprises in China: Comparison between Japan and Taiwan

This paper explores the location choice of MNEs in China, shedding special light on the role of agglomeration of same-nationality firms. In particular, we examine how its role differs according to investors’ productivity. Furthermore, we compare the location choice of Japanese and Taiwanese MNEs in China, because Taiwanese MNEs are expected to experience less uncertainty in investing in China than Japanese MNEs, due to Taiwan’s linguistic and cultural advantages in China. We find that, less productive Japanese firms prefer to locate close to larger same-nationality agglomerations, there are no differences in location according to firms’ productivity in the case of Taiwanese firms.

Lattice study on two-color QCD with six flavors of dynamical quarks

We study the dynamics of SU(2) gauge theory with NF=6 Dirac fermions by means of lattice simulation to investigate if they are appropriate to realization of electroweak symmetry breaking. The discrete analogue of beta function for the running coupling constant defined under the Schroedinger functional boundary condition are computed on the lattices up to linear size of L/a=24 and preclude the existence of infrared fixed point below 7.6. Gluonic observables such as heavy quark potential, string tension, Polyakov loop suggest that the target system is in the confining phase even in the massless quark limit.Comment: 7 pages, 9 figures, Proceedings of The 30th International Symposium on Lattice Field Theory, June 24-29, 2012, Cairns, Australi
