Homework Help: A question about kaon masses and decay widths

  1. Apr 20, 2014 #1
    1. The problem statement, all variables and given/known data

    Ok, so I need to make a software that will simulate a neutral kaon system, and I only have the following data about the masses and decay widths:

    gammaS = 580*gammaL {S = short lived state, L = long lived state}

    mS - mL = 0.477*gammaS

    2. Relevant equations

    How to implement these numerically in a program? (i.e. what values to give each of the four terms)

    3. The attempt at a solution

    I tried

    gammaS = 580
    gammaL = 1
    mS = 277.6
    mL = 1

    doesn't work :(

    What do you mean by

    I tried

    gammaS = 580
    gammaL = 1
    mS = 277.6
    mL = 1
    " ?

    What do you mean by " doesn't work :(" ?

    You haven't really told us anything...

    I need to parametrize these values in order to verify a bell inequality, and the result that I get is not ok. This was my question, how can I parametrize these 4 values with the information above, because it seems that only the mL-mS difference is measured, but I haven't found mS and mL themselves.

    mL and mS are the Kaon mass.

    Dauto, I know they represent the masses of the short and long lived states. The problem is I cannot find their numerical values anywhere, only their difference. Does anyone know what are the specific values of ms and ml?

    L.E. Ok , so I managed to solve it and it works. Topic can be closed.

    In the future if you need data on any particles a good place to look is the particle data group (PDG) website
