• The clothed states of unstable particles are investigated on the basis of quantum field theory, and thereby a new mathematical notion, "complex distribution", is introduced. Then the exact eigenstate of total Hamiltonian with the complex eigenvalue, whose real part represents the mass of the unstable particle and whose imaginary part is interpreted as the half reciprocal of its lifetime, can be constructed by means of the complex distribution. But this state is not observable. The physical state of the unstable particle therefore is defined as an approximate state of the exact eigenstate, which exhibits physically reasonable behaviours.
