Changing one parameter, all parameters with dependencies will change?

Asked by Francisco Casalinho

Hello,

When we change the value of some parameter in the param.card ( after launch) , will all the parameters that depend on the previous parameter also change?

Example:
changing the Z boson mass -> the W mass and the square of the mixing angle are dependent of the Z mass

Thanks,

Francisco

This is the parameter ee defined wihtin the UFO model.
Different UFO model could defined ee in various way, so I can not be more precise.

In the default standard model this is the electric charge.

Cheers,

Olivier
