AB: The role of Landau damping on protons in dissipation of Alfven waves in the solar wind is studied. It is found that in a finite-beta plasma, Landau resonant interaction of oblique Alfven waves with protons can lead to their effective damping. The problem of power-law spectra of MHD waves in the solar wind plasma is discussed.
