Subleading terms in asymptotic Passarino-Veltman functions
نویسنده
چکیده
We write explicit and self-contained asymptotic expressions for the tensorial B, C and D Passarino-Veltman functions. These include quadratic and linear logarithmic terms, as well as subleading constant terms. Only mass-suppressed O(m2/s) contributions are neglected. We discuss the usefulness of such expressions, particularly for studying oneloop effects in 2-to-2 body processes at high energy. PACS numbers: 11.15.Bt, 12.15.Lk, 12.60.Jv

Prototype Graphs for Radiative Corrections to Polarized Chargino or Neutralino Production in Electron-Positron Annihilation
We present the contributions from all types of one-loop corrections to the scattering amplitude for the pair production of polarized charginos or neutralinos from polarized electron-positron annihilation. The contributions are classified in terms of “prototypes” distinguished by the number of particles inside the loops and their spins. The results are quoted in terms of the Veltman-Passarino fu...
متن کاملLight-by-light scattering in SANC
In this paper we describe the implementation of the QED process γγ → γγ through a fermion loop into the framework of SANC system. The computations of this process takes into account non-zero mass of loop-fermion. We briefly describe additional precomputation modules used for calculation of massive fermion-box diagrams. We present the covariant and helicity amplitudes for this process and also s...

We briefly sketch the methods for a numerically stable evaluation of tensor one-loop integrals that have been used in the calculation of the complete electroweak one-loop corrections to e + e − → 4 fermions. In particular, the improvement of the new methods over the conventional Passarino–Veltman reduction is illustrated for some 4-point integrals in the delicate limits of small Gram (and other...
متن کاملAsymptotics of heavy-meson form factors
Using methods developed for hard exclusive QCD processes, we calculate the asymptotic behaviour of heavy-meson form factors at large recoil. It is determined by the leadingand subleading-twist meson wave functions. For 1 ≪ |v · v′| ≪ mQ/Λ, the form factors are dominated by the Isgur–Wise function, which is determined by the interference between the wave functions of leading and subleading twist...
متن کاملLight-cone distribution functions for B decays at subleading order in 1Õmb
We construct the higher twist structure functions that describe inclusive b hadron decays in regions of phase space where the hadronic decay products carry high energy but have low invariant mass. We show that, for B meson decays, there are four new nonvanishing matrix elements of nonlocal operators. We show that to subleading twist these decays are parametrized in terms of four functions. We c...
