W, Z PLUS JET PRODUCTION AT $p\bar p$  COLLIDERS

We present the calculation of the master integrals needed for the two-loop QCD×EW corrections to q +q → l − + l + and q +q → l − + ν , for massless external particles. We treat the W and Z bosons as degenerate in mass. We identify three types of diagrams, according to the presence of massive internal lines: the no-mass type, the onemass type, and the two-mass type, where all massive propagators, when occurring, contain the same mass value. We find a basis of 49 master integrals and evaluate them with the method of the differential equations. The Magnus exponential is employed to choose a set of master integrals that obeys a canonical system of differential equations. Boundary conditions are found either by matching the solutions onto simpler integrals in special kinematic configurations, or by requiring the regularity of the solution at pseudothresholds. The canonical master integrals are finally given as Taylor series around d = 4 spacetime dimensions, up to order four, with coefficients given in terms of iterated integrals, respectively up to weight four.

“…More exclusive observables are known in the literature. The Z and W production at non-zero transverse momentum p T is known at the NLO in QCD [21][22][23][24][25][26] and in the full SM [27]. The two-loop QCD helicity amplitudes for the production of a Z or a W with a photon have also been calculated [28].…”

Zwei andere Reaktionen der Hydrazone, die zu Azohydrazinen fuhren, wurden ausgehend von der Aminonitrenhypothese entdeckt und konnten so als gewichtige Bestatigung dafur angesehen werden. Die Frage nach den Aminonitrenen, ihrer Bildung und ihren Umwandlungen wie auch die Frage nach den interessanten Eigenschaften der Azohydrazine [32] gehen bereits uber den Rahmen dieser Arbeit hinaus.

We construct event generators for pji-W'X-e+vX and pp+ZOX-+e+e -X including complete O ( a , ) corrections, and interface with initial-and final-state parton showers. Problems with negative weights and double-counting multiple-parton emissions are averted. We calculate the qT( W ) spectrum at both V' y =0.63 TeV and V'; = 1.8 TeV, and compare with data and other theoretical predictions. We also present cross sections for the various W or Z plus multijet event topologies and compare with matrix-element results. We show several distributions associated with W +multijet events and find the jet rapidity distribution can be used to test the validity of our approach.

W, Z PLUS JET PRODUCTION AT $p\bar p$ COLLIDERS

Abstract: We have calculated cross sections for the production of W± and Z bosons in association with one and two jets at [Formula: see text] collider energies. The rates for these processes in second-order QCD are compared with jet rates measured by UA1 and CDF.
