A smaller α s in the MIT bag model: The Coulomb-spike effect

A smaller α s in the MIT bag model: The Coulomb-spike effect We show that the value of α s found in the zeroth-order MIT bag model is an overestimate, due to the neglect of a short-distance spike in quark wave functions which the color Coulomb force produces. The formation of the spike in the bag is studied here primarily in c c ― states. We argue that short-distance processes calculated in the bag e.g., Γ ( q q ― → e + e - ) and the proton decay rate have been underestimated through this effect. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)

Abstract

We show that the value of α s found in the zeroth-order MIT bag model is an overestimate, due to the neglect of a short-distance spike in quark wave functions which the color Coulomb force produces. The formation of the spike in the bag is studied here primarily in c c ― states. We argue that short-distance processes calculated in the bag e.g., Γ ( q q ― → e + e - ) and the proton decay rate have been underestimated through this effect.
