Nature of Particle Decay

  1. Jun 27, 2011 #1
    What drives particle decay? Is it an elementary, irreducible observation or can we model it based on a set of observable variables?

    Do all particle decay modes involve the weak force? Does one even need the intervention of a given force to have particle decay?

    Does string theory explain decay in terms of things like string tension, oscillation, etc?

    Beta decay (and related processes) are governed by the weak force. Alpha decay and fission are strong plus em force results.
