Randall-Sundrum Model and Applications

Abstract

The Randall Sundr um model (RS) was prcsenl.c<1 in 1999 to solve the '-(iggs hierarchy problem of the parLicle physics. This model created interest. in the phenomenologist and theoret.icians to work in the e..'X Lra dimensions scenarios. In the PI'CSCIl l. dissertation we will examine the rarc decay Ab ~ Al+(- in the context of 8M and RS model with custodial protection, We compute the physical obsen'ables like, difrer ential branching raLia, forward-backward llSY Il'UllCl.ries llnd polarization asymmetries of /I. baryoll in Sivi and HSr. model. By llsing low energy effective Hamiltonian the ha.dronic matrix elements pa rametrized by form factors that arc calc ul at.cd by QeD sum rules.
