public class GlashowResonanceHadronic
extends GlashowResonanceLeptonic
implements Function

The Glashow Resonance reaction with W into the hadronic decay

   \bar{nu_e} + e^{-1} -> hadrons
   

The super class GlashowResonanceLeptonic class is used in most of the calculation The inelasiticity parameter y is fixed to be always 0 because all the final states are hadrons that generates cascades at once.

setIncidentParticleEnergy

public void setIncidentParticleEnergy(double energy)

        Set The incident particle energy [GeV].
        The default value has been given by the constructor
        Interactions( ) with p.getEnergy( ) where p is 
        the Particle class. You might want to set, however,
        a different value such as 
        logE = logEnergyMinimum + deltaLogE*ilogE
        where ilogE is i'th index of the logEnergyMatrix
        in the Particle class p. This method provides you
        with a way to put the incident particle energy.
