چکیده

We reemphasize that the ratio $R_{s\mu} \equiv \overline{\mathcal{B}}(B_s\to\mu\bar\mu)/\Delta M_s$ is a measure of tension Standard Model (SM) with latest measurements $\overline{\mathcal{B}}(B_s\to\mu\bar\mu)$ does not suffer from persistent puzzle on $|V_{cb}|$ determinations inclusive versus exclusive $b\to c\ell\bar\nu$ decays and which affects value CKM element $|V_{ts}|$ crucial for SM predictions both $\Delta M_s$, but cancels out in $R_{s\mu}$. In our analysis we include higher order electroweak QED corrections und adapt hadronic input to find about $2\sigma$ $R_{s\mu}$ independently $|V_{ts}|$. also discuss $R_{d\mu}$ could turn out, particular correlation $R_{s\mu}$, be useful search New Physics, when data ratios improves. Also independent or more precisely $|V_{td}|$.

Superdeduction in Lambda-Bar-Mu-Mu-Tilde

Superdeduction is a method specially designed to ease the use of first-order theories in predicate logic. The theory is used to enrich the deduction system with new deduction rules in a systematic, correct and complete way. A proof-term language and a cut-elimination reduction already exist for superdeduction, both based on Christian Urban’s work on classical sequent calculus. However the compu...

A Fuzzy - Controlled Delta - Bar - Delta LearningruleW

| In classic backpropagation nets, as introduced by Rumelhart et al. 1], the weights are modiied according to the method of steepest descent. The goal of this weight modiication is to minimise the error in net-outputs for a given training set. Basing upon Jacobs' work 2], we point out drawbacks of steepest descent and suggest improvements on it. These yield a backpropagation net, which adjusts ...
