phi-meson in Nuclear Matter
-meson mass in nuclear matter () is investigated using an
effective Lagrangian of interacting with octet baryons.
decreases by a few \% in nuclear matter due to the current conservation and
effective nucleon/hyperon masses. Its implication to the p-A and A-A collisions
are briefly discussed.Comment: 7 pages, latex, 3 postscript figures, submitted to Prog. Theor. Phy
Localization of affine W-algebras
We introduce the notion of an asymptotic algebra of chiral differential
operators. We then construct, via a chiral Hamiltonian reduction, one such
algebra over a resolution of the intersection of the Slodowy slice with the
nilpotent cone. We compute the space of global sections of this algebra thereby
proving a localization theorem for affine W-algebras at the critical level.Comment: 36 page
