New physics effects to the lepton polarizations in the B -> K l^+ l^- decay [PDF]

open access: yes, 2001
Using the general, model independent form of the effective Hamiltonian, the general expressions of the longitudinal, normal and transversal polarization asymmetries for (l^-) and (l^+) and combinations of them for the exclusive (B -> K l^+ l^-) decay are

Additions to the genus Lessingianthus (Asteraceae, Vernonieae) from South America

open access: yesRodriguésia
Two new species of Lessingianthus (Asteraceae: Vernonieae) are described and illustrated. One of these, L. foliosus Dematt., bears a resemblance to L. vepretorum, but can be separated from it by its linear leaves, that are lanate on the abaxial surface ...

General analysis of lepton polarizations in rare B -> K^* l^+ l^- decay beyond the standard model [PDF]

open access: yes, 2000
The general analysis of lepton polarization asymmetries in rare B -> K^* l^+ l^- decay is investigated. Using the most general, model independent effective Hamiltonian, the general expressions of the longitudinal, normal and transversal polarization ...
