Probing Noncommutative Space-Time Scale Using γγ→Z at ILC

  • In this talk we report our work on testing Noncommutative Space-Time Scale Using γγ→Z at ILC. In ordinary space-time theory, decay of a spin-1 particle into two photons is strictly forbidden due to the Yang's Theorem. With noncommutative space-time this process can occur. This process thus provides an important probe for noncommutative space-time. The γγ collision mode at the ILC provides an ideal place to carry out such a study. Assuming an integrated luminosity of 500fb-1, we show that the constraint which can be achieved on Γ(Z→γγ) is three to four orders of magnitude better than the current bound of 5.2×10-5GeV. The noncommutative scale can be probed up to a few TeVs.

Abstract: In this talk we report our work on testing Noncommutative Space-Time Scale Using γγ→Z at ILC. In ordinary space-time theory, decay of a spin-1 particle into two photons is strictly forbidden due to the Yang's Theorem. With noncommutative space-time this process can occur. This process thus provides an important probe for noncommutative space-time. The γγ collision mode at the ILC provides an ideal place to carry out such a study. Assuming an integrated luminosity of 500fb-1, we show that the constraint which can be achieved on Γ(Z→γγ) is three to four orders of magnitude better than the current bound of 5.2×10-5GeV. The noncommutative scale can be probed up to a few TeVs.
