Analytic Definition of Curves and Surfaces by Parabolic Blending

A procedure for interpolating between specified points of a curve or surface is described. The method guarantees slope continuity at all junctions. A surface panel divided into p x q contiguous patches is completely specified by the coordinates of (p+1) x (q+1) points. Each individual patch, however, depends parametrically on the coordinates of 16 points, allowing shape flexibility and global conformity.

Corrections to Fermi's Golden Rule in $ϕ\to K\bar{K}$ Decays

We analyze the decays $ϕ\to K\bar{K}$ utilizing a formulation of transition rates which explicitly exhibits corrections to Fermi's Golden Rule. These corrections arise in systems in which the phase space and/or matrix element varies rapidly with energy, as happens in $ϕ\to K\bar{K}$, which is just above threshold. We show that the theoretical corrections resolve a puzzling $5σ$ discrepancy between theory and experiment for the branching ratio $R = Γ(ϕ\to K^+K^-)/Γ(ϕ\to K^0\bar{K}^0)$.
