“The Pen is Mightier than the Sword”: Popular Ethics in Edo Period Japan

By the end of the Edo period of Japan 1603 1868 the three major religious traditions of Japan each appear to have found formally defined roles within Japanese culture and politics In the mid-19 th century N Sontoku 1787 1858 succinctly summarized his understanding of their more formalized roles as follows Shinto is the way which provides the foundation of the country Confucianism is the way which provides for governing the country and Buddhism is the way which provides for governing one s min

The exclusive rare decays B -> K l(bar) l and B_c -> D(D*) l(bar) l in a relativistic quark model

We study the exclusive rare decay B -> K l(bar) l. We calculate the relevant form factors within a relativistic constituent quark model, for the first time without employing the impulse approximation. The calculated form factors are used to evaluate differential decay rates and polarization observables. We present results on the q2-dependence of a set of observables with and without long-distance contributions. A similar analysis is done for the exclusive rare decays B_c -> D (D*) l(bar) l with special emphasis on the cascade decay B_c -> D* (-> D pi) l(bar) l. We derive a four-fold angular decay distribution for this process in terms of helicity amplitudes including lepton mass effects. The four-fold angular decay distribution allows to define a number of physical observables which are amenable to measurement. We compare our results with the results of other studies.Comment: 28 pages, 12 figure
