S and T for Leptoquarks and Bileptons
Paul H. Frampton, Masayasu Harada
We calculate contributions to the oblique parameters and for leptoquarks and bileptons, and find phenomenological constraints on their allowed masses. Leptoquarks suggested…
Constraints from Precision Electroweak Data on Leptoquarks and Bileptons
Paul H. Frampton, Masayasu Harada
Explicit expressions are derived for the oblique parameters and in certain extensions of the standard model. In particular, we consider leptoquarks and bileptons, and find…
Generalization of the Bound State Model
Masayasu Harada, Francesco Sannino, Joseph Schechter +1
In the bound state approach the heavy baryons are constructed by binding, with any orbital angular momentum, the heavy meson multiplet to the nucleon considered as a soliton in an…
Existence of sigma meson in pi-pi scattering
Masayasu Harada
In this talk I summarize a recently proposed mechanism to understand pi pi scattering to 1 GeV. The model is motivated by the 1/Nc expansion to QCD, and includes a current algebra…
