The Principle of Maximum Conformality
A key problem in making precise perturbative QCD predictions is the uncertainty in determining the renormalization scale of the running coupling αs(μ ). It is common practice to guess a physical scale μ = Q which is of order of a typical momentum transfer Q in the process, and then vary the scale over a range Q/2 and 2Q. This procedure is clearly problematic since the resulting fixed-order pQCD...

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...

We review recent progress at the two e + e − B factories. The first measurement of CP violation and the prospects for measuring all the angles of the unitarity triangle are discussed.
متن کاملSemileptonic B Decays at the B Factories
Semileptonic B decays provide direct access to the CKM matrix elements Vub and Vcb, whose ratio gives a measurement of the side of the Unitarity Triangle opposite the angle β. The underlying theory of semileptonic B decays is at an advanced stage. The weak currents factorize in leptonic and hadronic parts which do not interact between each other. Moreover, the b quark mass is considerably large...
