(Non-)mixing of K vector bosons

  1. Dec 14, 2011 #1
    Why dont the vector bosons K(0*) and K-bar(0*) mix the way the pseudo-scalar bosons,
    K(0) and K-bar(0) do?

    Please calculate the lifetime of the K* in units of the Kshort lifetime. Is the answer obvious now?

    I dont know how to do the suggested calculation -- I was expecting some sort of selection rule to apply

    Is the idea that the K* just decays too quickly into Kπ by a strong interaction?

    Bingo.

    And you do know how to do the calculation. Look up both numbers and divide.
