The method of QCD light-cone sum rules is used to calculate soft nonfactorizable contributions to the decay amplitude for B → J/ψK. The result confirms expectations that in color-suppressed decays nonfactorizable corrections can be sizable.

We report our calculations on the logarithmic slope of the diffractive structure function F D 2 considering distinct approaches coming from both the pQCD and the Regge descriptions of diffractive DIS. Such a quantity is a potential observable to discriminate between pQCD and Regge domains and allows to disentangle the underlying dynamics.

We argue that there are no axially symmetric rotating monopole solutions for a Yang-Mills-Higgs theory in flat spacetime background. We construct axially symmetric Yang-Mills-Higgs solutions in the presence of a negative cosmological constant, carrying magnetic charge n and a nonvanishing electric charge. However, these solution are also nonrotating.
