First-principles studies of the structural and electronic properties of poly-para-phenylene vinylene (2004)
Journal Article

We present first-principles investigations of the structural and electronic properties of PPV in both the isolated chain and the crystalline state. The calculations are mainly based on the local density approximation within density functional theory....

We have studied the ortho, para, and, in the case of D3+, meta forms of the multiply-deuterated isotopes of H3+, under physical conditions believed to be appropriate to pre-protostellar cores. As deuterons have integral nuclear spin, I = 1, Bose-Eins... Read More about Multiply-deuterated species in prestellar cores.

MHV rules for Higgs plus multi-gluon amplitudes (2004)
Journal Article

We use tree-level perturbation theory to show how non-supersymmetric one-loop scattering amplitudes for a Higgs boson plus an arbitrary number of partons can be constructed, in the limit of a heavy top quark, from a generalization of the scalar graph...

We propose a more physical parameterization of the gluon distribution for global parton analyses of deep inelastic and related hard scattering data. In the new parameterization the gluon distribution at large x in the -scheme is driven by the valence... Read More about Physical gluons and high-ET jets.

We present a complete calculation of the contributions to the effective leptonic weak mixing angle, sin2, generated by closed fermion loops at the two-loop level of the electroweak interactions. This quantity is the source of the most stringent bound...
