Elementary particles are supposed not to be configured from other particles. However, elementary particles can still annihilate. When they annihilate, the process produces photons. Photons also have particle behavior. Is this a contradiction?
Elementary particles are supposed to be point-like objects. Are all point-like objects elementary particles?
The Higgs particle is supposed to be an elementary particle. Still, it decays into other objects. These objects need not be photons. Is it wrong to consider the Higgs particle as an elementary particle?
Are higher generation particles such as muon and tau elementary particles?
Can elementary particles only exist as fermions and are massive bosons always composites?
