J/psi Production at LEP: Revisited and Resummed
C. Glenn Boyd, Adam K. Leibovich, Ira Z. Rothstein
We present the leading order differential and total rates for J/ψproduction at LEP. By leading order we mean all terms of the form alpha_s[alpha_s log(M_Z^2/M_{psi}^2)]^n and alpha…
The Phenomenology of Inclusive Heavy-to-Light Sum Rules
C. Glenn Boyd, I. Z. Rothstein
By calculating the O(α_s) corrections to inclusive heavy-to-light sum rules we find model independent upper and lower bounds on form factors for B to pi and B to rho. We use the bo…
Precision Corrections to Dispersive Bounds on Form Factors
C. Glenn Boyd, Benjamin Grinstein, Richard F. Lebed
We present precision corrections to dispersion relation bounds on form factors in bottom hadron semileptonic decays and analyze their effects on parameterizations derived from thes…
Analyticity, Shapes of Semileptonic Form Factors, and B to pi l nu
C. Glenn Boyd, Martin J. Savage
We give a pedagogical discussion of the physics underlying dispersion relation-derived parameterizations of form factors describing B -> pi l nu and B -> D l nu. Moments of the dis…
Heavy Baryon Mixing in Chiral Perturbation Theory
C. Glenn Boyd, Ming Lu, Martin J. Savage
We discuss the SU(3) and heavy quark spin-symmetry breaking mixing between the Xi_c and Xi'_c charmed baryons. Chromomagnetic hyperfine interactions are the leading source of spin-…
