متن کاملUltra-violet Finite Noncommutative Theories
We establish the ultraviolet finiteness of various classes of noncommutative gauge theories.
متن کاملUltra-violet Finiteness in Noncommutative Supersymmetric Theories
We consider the ultraviolet divergence structure of general noncommutative super-symmetric U (N c) gauge theories, and seek theories which are all-orders finite. September 2001
متن کاملUltra-Violet Behavior of Bosonic Quantum Membranes
We treat the action for a bosonic membrane as a sigma model, and then compute quantum corrections by integrating out higher membrane modes. As in string theory, where the equations of motion of Einstein’s theory emerges by setting β = 0, we find that, with certain assumptions, we can recover the equations of motion for the background fields, i.e. Rμν +(1/4)FμαβγμF αβγ ν = 0 and DFαβγ = 0. for t...
متن کاملAn Ultra-violet Light Monitor for Spear3
A synchrotron light monitor is an essential tool for operating a storage ring. For SPEAR3, the upgrade of the SPEAR storage ring, the light monitor was designed not only for monitoring the beam presence but also to measure beam parameters. To minimize diffraction effects, UV light around 200 nm is used to image the electron source rather than visible light. At 200 nm, the rms diffraction spot i...
