Analytic two–loop virtual corrections to b → dll
نویسنده
چکیده
We compute the two–loop virtual corrections to the flavour changing neutral current process b → dl+l−. As calculation techniques integration by parts identities and the method of differential equations are used. The result is presented in closed form as a function of q/mb , where q 2 is the invariant mass of the lepton pair and mb is the b–quark mass.

Dual Phase Detector Based Delay Locked Loop for High Speed Applications
In this paper a new architecture for delay locked loops will be presented. One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...
متن کاملOne-loop QCD corrections to quark scattering at NNLO∗
We present the O(α s) virtual QCD corrections to unlike-quark qq̄ → q q̄ and like-quark scattering qq̄ → qq̄ due to the interference of one-loop amplitudes with one-loop amplitudes. The structure of the infrared divergences agrees with that predicted by Catani. The results are expressed in an analytic form so that the relevant expressions for crossed scattering processes can be obtained in a straig...
متن کاملTwo - loop electroweak corrections at high energies †
We discuss two-loop leading and angular-dependent next-to-leading logarithmic electroweak virtual corrections to arbitrary processes at energies above the electroweak scale. The relevant Feynman diagrams involving soft-collinear gauge bosons γ,Z,W have been evaluated in eikonal approximation. We present results obtained from the analytic evaluation of massive loop integrals. To isolate mass sin...
متن کاملLow Settling Time All Digital DLL For VHF Application
Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...
متن کاملTwo-loop QCD corrections to gluon-gluon scattering∗
We present the O (α s) virtual QCD corrections to gluon-gluon scattering due to the interference of tree and two-loop amplitudes. We work in conventional dimensional regularisation and give analytic expressions renormalised in the MS scheme. The structure of the infrared divergences agrees with that predicted by Catani while formulae for the finite remainder are given in terms of logarithms and...
