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 p...

در این پایان نامه ما فرمول صریحی از s-انحنا در فضای راندرز همگن ارائه می دهیم. برای اینکار روی فضای برداری n-بعدی v و نیز فرم مینکویسکی f، کمیت ?_f=(vol(b^n))/(vol{(y^i)?r^n |f(y^i b_i )<1}) را تعریف می کنیم و با استفاده از آن کمیت پیچیدگی از (v,f) را به فرم,y?v-{0} ?(y)=ln ?(det?(g_ij (y)))/?_f تعریف می کنیم.برای هر y?t_x m-{0} فرض می کنیم ?(t) یک ژئودزیک با شرط ?(0)=x ,(?(0)=y) ? ...

We construct various examples of 14 -BPS giant gravitons embedded into the type IIB supergravity background AdS3×S +×S −×S with pure R-R flux: two D1-brane giants wrapping 1-cycles in AdS3 and S 3 +×S −, and one D5-brane giant wrapping a 4-cycle in S3 + × S3 − and the S1. These D-branes are supported by angular momenta αP on one 3-sphere and (1−α)P on the other. We then construct a general clas...
A study of charm fragmentation into D∗+ s and D + s in e +e− annihilations at √ s = 10.5 GeV is presented. This study using 4.72±0.05 fb−1 of CLEO II data reports measurements of the cross-sections σ(D∗+ s ) and σ(D + s ) in momentum regions above x = 0.44, where x is theDs momentum divided by the maximum kinematically allowed Ds momentum. The Ds vector to vector plus pseudoscalar production ra...
It has been suggested that the observed Ds −D 0 lifetime difference can be ‘understood’ as due to SU(3)F l breaking in the phase spaces for the exclusive D 0 channels ‘removing’ the need for weak annihilation. It is pointed out that several of the statements in this argument are misleading or even inconsistent with a state-of-the-art description of heavy flavour decays based on the operator pro...
Within the Standard Model, leptonic D (or B) meson decays proceed via annihilation of the initial state quarks. The matrix element is described by the product of a hadronic current, a leptonic current, along with a W propagator. The form of the latter two are well-known within the Standard Model, however, the hadronic matrix element, which represents the annihilation of the initial state heavy ...
