technical and legal parameters for determination of river boundary,( case study haraz river)

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...

Bs Decays and Mixing

Bs−Bs mixing with a chiral light quark action

We study the B 0 s − B 0 s mixing amplitude in Standard Model by computing the relevant hadronic matrix element in the static limit of lattice HQET with the Neuberger light quark action. In the quenched approximation, and after matching to the MS scheme in QCD, we obtain B MS B s (m b) = 0.940(16)(22). c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCom...

Bs, Bc and b-baryons

We present the latest measurements on masses, lifetimes and branching fractions for the Bs and Bc mesons as well as for b-baryons. For the Bs meson we discuss as well the latest results on mixing. These results were produced by the CDF and D0 experiments at Fermilab or by earlier LEP and PEPII experiments.

DETERMINATION OF THE CP VIOLATING PHASE γ BY A SUM OVER COMMON DECAY MODES TO Bs AND ¯ Bs

To help the difficult determination of the angle γ of the unitarity triangle, Aleksan, Dunietz and Kayser have proposed the modes of the type K − D + s , common to B s and ¯ B s. We point out that it is possible to gain in statistics by a sum over all modes with ground state mesons in the final state, i.e. s. The delicate point is the relative phase of these different contributions to the dilut...
