.discovered by Fermi
.particles with half-integer spin quantum numbers i.e s=1/2
e.g-electron,proton,neutron.
.discovered by Satyendra Nath Bose
.particles with zero or integer spin quantum number
eg.photon
particles on which the "strong force"acts are called hadrons.
particles on which "strong force" do not act, "weak force " is the dominent force acting on it.
.assembly/pair/combination of antiparticles(e.g.positron for electron and antiproton for proton)
therfore-positron/antiproton combination is an antimatter.
.when a particle meet its antiparticle,the two can annihilate each other and their combined energies reappear in another forms.
e. g e(-)+e(+)---->y(gamma)+y(gamma).
p+p(-)---->4π +4π-.
