The covariant structure of the self-force of a particle in a general curved background has been elucidated in the cases of scalar, electromagnetic, and gravitational charges. Specifically, what weâ€¦ (More)

1 Abstract Lattice QCD calculation of s-wave hadron scattering lengths in the channels Ï€-Ï€, Ï€-N, K-N, Â¯ K-N and N-N is carried out in the quenched approximation at Î² = 6/g 2 = 5.7. A variant of theâ€¦ (More)

Using the Teukolsky and Sasaki-Nakamura formalisms for the perterbations around a Kerr black hole, we calculate the energy flux of gravitational waves induced by a spinning particle of mass Î¼ andâ€¦ (More)

An exploratory study is made of the nucleon-nucleon s-wave scattering lengths in quenched lattice QCD with the Wilson quark action. The Ï€-N and Ï€-Ï€ scattering lengths are also calculated forâ€¦ (More)
