B-meson One of the heaviest mesons , containing a bottom quark . Strong Force A force which binds quarks together. Its range is limited to the distances between quarks in hadrons , but an indirect effect of the strong force is to bind protons and neutrons together to form nuclei. The strong force is carried by gluons . A force with infinite range which acts between objectsaccording to their charge.
Specific cases are the electric and magnetic forces.
The electromagnetic force is carried by photons . The weak force is the only one that affects neutrinos . Electroweak Force A force resulting from the combination of the electromagnetic force and the weak force . Gravity A force with infinite range which acts between objects, such as planets,according to their mass. Gluons The carrier particle of the strong force .
