A first glance to the kinematic moments of B ? Xc?? at third order
نویسندگان
چکیده
A bstract We study the impact of third-order QCD corrections for several kinematic moments inclusive semileptonic B decays, to first order in 1 /m b expansion. consider four charged-lepton energy E R spectrum, total leptonic invariant mass q 2 and hadronic $$ {M}_X^2 M X 2 . No experimental cuts are applied. Our analytic results obtained via an asymptotic expansion around limit m ~ c After converting scheme bottom kinetic we compare size higher contributions from / {m}_b^2 m b {m}_b^3 3 power relative uncertainties.

15 صفحه اولThe perception of spatial order at a glance
Spatial order is the organizing principle of the visual areas in the brain. But to what extent does this spatial mapping help us see where things are? Observers trained to perfectly recall the spatial order of seven items presented simultaneously for 5 s were asked to report their order when flashed for only 150 ms. We found that the capacity for perceiving the order of these brief stimuli was ...

Protein kinase B/Akt at a glance.
Among the signalling proteins that respond to a large variety of signals, protein kinase B (PKB, also known as Akt) appears to be a central player in regulation of metabolism, cell survival, motility, transcription and cell-cycle progression. Conserved from primitive metazoans to humans, PKB belongs to the AGC subfamily of the protein kinase superfamily, which consists of 518 members in humans ...
