Adding a Myers Term to the IIB Matrix Model

ArXiv hep-th/0310170 (2003)

Authors:

Peter Austing, John F Wheater

Abstract:

We show that Yang-Mills matrix integrals remain convergent when a Myers term is added, and stay in the same topological class as the original model. It is possible to add a supersymmetric Myers term and this leaves the partition function invariant.

Electroweak production of hybrid mesons in a flux-tube simulation of lattice QCD.

Phys Rev Lett 91:14 (2003) 142001

Authors:

FE Close, JJ Dudek

Abstract:

We make the first calculation of the electroweak couplings of hybrid mesons to conventional mesons appropriate to photoproduction and to the decays of B or D mesons. E1 amplitudes are found to be large and may contribute in charge exchange gammap-->nH(+) allowing production of (among others) the charged 1(-+) exotic hybrid off a(2) exchange. Axial hybrid meson photoproduction is predicted to be large courtesy of pi exchange, and its strange hybrid counterpart is predicted in B-->psiK(H)(1(+)) with branching ratio B approximately 10(-4). Higher multipoles and some implications for hybrid charmonium are briefly discussed.
