The velocity space diffusion equation which describes a distortion of the velocitydistribution function due to nonlinear Landau damping of electrostatic waves in aplasma without magnetic field is derived from the Vlasov-Maxwell equations by perturbation theory. The conservation laws for total energy and momentum densities ofwaves and particles are verified, and the time evolutions for energy and momentumdensities of particles are given by means of nonlinear wave-particle couplingcoefficient in kinetic wave equation. The obtained equations can be also available foranalysis of energy transfer between waves and particles caused by nonlinear Landaudamping due to non-magnetized particles in a magnetized plasma.[velocity space diffusion, nonlinear Landau damping, induced scattering, elec- ll trostatic waves,energy conservation,momentum conservation,energy transfer, ll theoryl
