Two Body Bound State in Non Commutative Space Time Morteza Khorsandi Shirghan mortezakhorsandi86@yahoo com 2012 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran Supervisor Dr Mansour Haghighat mansour@cc iut ac ir Advisor Dr Moslem Zarei Zarei@ph iut ac ir 2010 MSC 05C15 53C42 Keywords Noncommutative space time Standard model Hydrogen atom Lamb shift Noncom mutative parameter Abstract In this thesis after introducing noncommutative space time rst we give a brief review on two ap proach of noncommutative standard model NCSM In the rst approach the gauge group is restricted to U n and the symmetry group of the standard model is achieved by reduction of U 3 U 2 U 1 to SU 3 SU 2 U 1 by an appropriate symmetry breaking In the second one the noncommu tative standard model based on SU 3 SU 2 U 1 gauge group and Seiberg Witten maps for the eld contents of the theory To investigate phenomenological aspects of these two approaches we study hydrogen atom spectrum and show that for the case space time i0 0 noncommutativity 2 the hydrogen atom has a noncommutative correction at the tree level of the order of 24 8 T eV Since parameter of noncommutativity is constant there is a preferred direction in space time which leads to the lorentz symmetry violation However in the investigations done in varied coecients of Lorentz violation in dierent tests very strong bounds are set on it so that in low energies Lorentz symmetry is an accurate symmetry of nature Therefore we study the lorentz conserving NCSM based on SU 3 SU 2 U 1 In this model we show that the hydrogen atom spectrum has a noncommutative correction at the tree level of the order of LCN C 1 15GeV Finally we generalize the obtained results to the muonic hydrogen atom p We show that in the LCNC there is a shift of the order of 0 11 meV in 2S 2P transition in p The obtained result is comparable with di erence between the theoretical and the experimental value for p lamb shift 0 3meV
