Weak leptonic decays of light and heavy pseudoscalar mesons are studied in a field-theoretic quark model where the mesons are described by constituent quarks and antiquarks with a particular ansatz and a Harmonic oscillator wave function. With constituent quark masses and Harmonic oscillator radii for mesons as parameters of the model, decay constants are calculated and found as (fπ, fk, fD, fB) = (132 MeV , 161 MeV , 160 MeV , 115 MeV ) indicating a reasonable agreement with the experimental data wherever available. Partial decay widths and branching ratios for kinematically allowed leptonic decay processes are also estimated and compared with the experiments wherever available.

Richard Feynman

As a student and later research fellow working with Richard Feynman at Caltech in the period 1969–74, I was in the happy situation of getting him interested in the quark model. This resulted in the construction of the relativistic harmonic oscillator quark model with the proviso of involving as few parameters and ad hoc assumptions as possible. The detailed predictions of the model and in particular for the nucleon photoproduction amplitudes were so good that in Feynman’s mind the quarks were to be considered real particles and identified by the partons seen in deep inelastic scattering. This article is a short account of my part in those developments and my collaboration with Feynman.
