Idea

In particle physics, matter is a bound state of fermionic particles.

This is in contrast to force fields, whose quanta are bosonic particles.

In the standard model of particle physics, all matter fields are sections of a spinor bundle on spacetime which is associated of a U(1)×SU(2)×SU(3)U(1) \times SU(2) \times SU(3)-principal bundle.

In the standard model of cosmology matter is characterized as part of the energy-momentum density with specific parameter of state w=p/ρw = p/\rho, see at FRW model.
