Astro-Particle Physics

Abstract

The fluctuation of space-time may be detected at small distances. Namsrai [Namsrai 1996] analysed the experimental data for scattering and got a limit of the fundamental length the length scale of fluctuation, as of the order of 10⁻³¹ cm i e., larger than Planck length. The stochastic nature of space-time can be revealed at ultra high energy interactions of elementary particles. The spectrum of highest energy cosmic ray primary proton is one of the challenging problems in astroparticle physics. In a recent work it has been shown [Roy 1995] that frame dependence of the scattering matrix (which is related to the fluctuation of space-time) shed new light on this problem.
