singlet Higgs production in electron and positron collision in noncommutative space time Elham Izadi Garmaseh Date of submission 2012 02 19 Department of Physics Isfahan University of Te nology Isfahan 84156 83111 IranDegree M Sc Language PersianSupervisor Prof Dr M Haghighat mansour@cc iut ac irAbstractIn this thesiss we will rst study the standard model in ordinary space then noncommutative space time and the standard model in this space are discussed In this framework there are two approa es In the rst one the symmetry group is U 3 U 2 U 1 whi can be reduced to the standard modelgroup SU 3 SU 2 L U 1 Y via two spontaneous symmetry breaking In the second approa the symmetry group is similar to the group in the ordinary standard model Meanwhile the NC elds through the seiberg Wi en maps are determined as functions of the NC parameter Followingwe generalize the standard model Higgs in doublet and singlet and to consider singlet Higgs photonvertex and nally we will calculate cross section of processes e e s s and will compare limiton with result of the paper of dark ma er Keywords singlet Higgs boson standard model noncommutative standard model
