Precision determination of Vub
We review how to determine |Vub| from inclusive semileptonic B decay using combined cuts on the leptonic and hadronic invariant masses to eliminate the b → c background. This leads to a determination of |Vub| with theoretical uncertainty at the 5–10% level. LBNL-49079, UCSD/PTH 01-22, UTPT-01-13 The magnitude of Vub determines the length of one of the side of the unitarity triangle and is there...
متن کاملPrecision Determination of |v Ub |
The last two years saw an impressive improvement in the determination of |Vub|, especially from inclusive decays. The error on inclusive |Vub| was reduced from 18% (PDG 2004) to 8% (PDG 2006). This progress is a result of a combined experimental and theoretical efforts. In this talk, the theoretical framework (BLNP) that enabled such progress is reviewed, as well as other approaches to inclusiv...

Figure 1: The unintegrated gluon distribution at a scale q̄ = 4 GeV for different values of μ and σ of the intrinsic k⊥ distribution as a function of x for fixed k⊥(top) and as a function of k⊥ (bottom) for fixed x Unintegrated parton density functions (uPDFs) are best suited to study details of the hadronic final state in high energy ep and also in pp collisions (for a review see [2–8]). In gen...
متن کاملDetermination of A Priori Decision Thresholds
|Speaker veriication systems are often compared based on an equal error rate (equal chance of false acceptance and false rejection) obtained by adjusting a decision threshold during veriication. However, the threshold should be found before veriication because the identity of a claimant is actually unknown in real-world situations. This paper presents a novel method to determine the decision th...
متن کاملDetermination of Intensity Thresholds via Shape Gradients
Shape analysis is a vital aspect of medical imaging. The shapes of objects in an image provide high-level information that is essential for many image processing tasks. Accurate analysis of medical images is often dependent upon an appropriate greyscale thresholding of the image for reliable feature extraction. The determination of object thresholds can be a time-consuming task because the thre...
