Homework Help Overview

The discussion revolves around the simulation of a neutral kaon system, focusing on the masses and decay widths of the short-lived and long-lived kaon states. Participants are exploring how to numerically implement given relationships between these parameters.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the values assigned to gammaS, gammaL, mS, and mL, questioning the validity of these assignments and their implications for the simulation. There is a specific inquiry about how to parametrize these values based on limited available data.

Discussion Status

The discussion includes attempts to clarify the numerical values of kaon masses and their differences. One participant indicates they have resolved their issue, suggesting some productive direction was achieved, although the specifics of the resolution are not detailed.

Contextual Notes

Participants note the challenge of finding specific numerical values for mS and mL, as only their difference is readily available. There is mention of a resource (the particle data group website) for future reference regarding particle data.

Homework Statement



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


Homework Equations



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

The Attempt at a Solution



I tried

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

doesn't work :(

What do you mean by

" ?

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
