THE PROCESS e e U    VIA VECTOR UNPARTICLE EXCHANGE IN THE RANDALL - SUNDRUM MODEL

Tóm tắt

In this work, the effects of vector unparticle on the process e e U   
in the Randall - Sundrum model is studied. Specifically, we calculate the crosssection for the process e e U    by s-channel and evaluated the cross-section as
a function of the center of mass energy s , cosine of scattering angle  , scaling
dimention
and the square of unknown coefficient of the unparticledU CU 2 operator OU . Our results reveal that the cross-section changes strongly when
1.9 2.0
  dU and its value is in the high energy domain much larger than the low
energy domain. The cross-section increases when C C C  2   U Z 2 2 . The differential
cross section has a maximum value at cos 1    and a minimum value at cos 0  
