Line Shapes of the Z(4430)

Eric Braaten, Meng Lu

The Belle Collaboration recently discovered the first manifestly exotic meson: Z^+(4430), which decays into psi' pi^+ and therefore has quark content c c-bar u d-bar. The proximity…

An Estimate of the Partial Width for X(3872) into p p-bar

Eric Braaten

We present an estimate of the partial width of X(3872) into p p-bar under the assumption that it is a weakly-bound hadronic molecule whose constituents are a superposition of the c…

The Effects of Charged Charm Mesons on the Line Shapes of the X(3872)

Eric Braaten, Meng Lu

The quantum numbers J^PC = 1++ of the X(3872) and the proximity of its mass to the D*0 anti-D0 threshold imply that it is either a loosely-bound hadronic molecule whose constituent…

SUSY Model Building

Stuart Raby

I review some of the latest directions in supersymmetric model building, focusing on SUSY breaking mechanisms in the minimal supersymmetric standard model [MSSM], the "little" hier…

Improved determination of color-singlet nonrelativistic QCD matrix elements for S-wave charmonium

Geoffrey T. Bodwin, Hee Sok Chung, Daekyoung Kang +2

We present a new computation of S-wave color-singlet nonrelativistic QCD matrix elements for the J/psi and the eta_c. We compute the matrix elements of leading order in the heavy-q…

Line Shapes of the X(3872)

Eric Braaten, Meng Lu

If the quantum numbers of the X(3872) are J^{PC}=1^{++}, the measurement of its mass implies that it is either a loosely-bound hadronic molecule whose constituents are a superposit…
