Mark all the hadrons. a) proton b) electron c)anti-top d) gluon e) tau neutrino

a) Proton

Explanation:

Proton belongs to the family of particles known as hadrons ,further classified as a baryon/hyperon.

Electron belongs to the family of particles known as fermions, further classified as a lepton.

Anti top quark belongs to the family of particles known as fermions, further classified as a quark.

Gluon belongs to the family of particles known as bosons, further classified as a guage.

Tau Neutrino belongs to the family of particles known as fermions, further classified as a lepton.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
