m_recoMethod

short GenParticle_p4::m_recoMethod

protected

switch to know which method to chose to better recover the original HepLorentzVector.

It is based on isTimelike(), isSpacelike(), isLightlike() and sign(ene) If m_recoMethod == 0: use HepLorentzVector::setVectM( 3vect(px,py,pz), m ) 1: use +(p**2 + m**2) to get the energy (where m**2 is signed) 2: use -(p**2 + m**2) to get the energy (where m**2 is signed) (ex: gluon with negative energy)

float GenParticle_p4::m_thetaPolarization

protected

polarization
