Abstract

Using the light cone QCD Sum Rules Method, we study the rare B --> gamma decay and find that the branching ratios are, B(B-s --> gamma) similar or equal to 7.5 x 10(-8) , B(B-d --> gamma) similar or equal to 4.2 x 10(-9). A comparison of our results on branching ratio with constituent quark and pole dominance model predictions are presented.
