Abstract We compute the next-to-leading virtual QCD corrections to the partonic cross section of the production of a Higgs boson in association with a Z boson in gluon fusion. The calculation is based on the recently introduced method of evaluating the amplitude via an expansion in terms of a small transverse momentum. We generalize the method to the case of different masses in the final state and of a process not symmetric in the forward-backward direction exchange. Our analytic approach gives a very good approximation (better than percent) of the partonic cross section in the center of mass energy region up to ∼ 750 GeV, where at the LHC ∼ 98% of the total hadronic cross section is concentrated.

In this paper, by using a Tsallis-Pareto-type function and the multisource thermal model, the elliptic flow coefficients of particles π±, K±, p+p¯, Λ+Λ¯, and KS0 produced in Pb–Pb collisions at the center-of-mass energy of sNN=5.02TeV are investigated. In the process of collisional evolution, because of geometric structure, pressure gradient, and thermal diffusion effects, deformation and translation occurred in the isotropic emission source, leading to anisotropy in the azimuth distribution of the final-state particles. Based on these dynamic factors, the dependence of elliptic flow on transverse momentum is described as well.

The anomalous [Formula: see text] coupling is probed through [Formula: see text] at the ILC. With a spectacular single lepton final state, this process is well suited to study the above coupling. Cross-section measurements can probe [Formula: see text] to about [Formula: see text] for a luminosity of 100 fb[Formula: see text] at 500 GeV center-of-mass energy with unpolarized electron beam. The limits derivable on [Formula: see text] from the total cross-section are comparatively more relaxed. Exploiting the energy-angle double distribution of the secondary muons, kinematic regions sensitive to these couplings are identified. The derivable limit on [Formula: see text] could be improved to a few per-mil, focusing on such regions. More importantly, the angular distributions at fixed energy values, and energy distribution at fixed angles present very interesting possibility of distinguishing the case of [Formula: see text] and [Formula: see text].

Linear Colliders

Taking account of the Randall-Sundrum model, we have evaluated the influence of model parameters in e e Z l l bb + − − + → →  collision at International Linear Colliders (ILC). In the ILC region, the total cross-section is enhanced at the 125 GeV radion. The total cross-section depends on the polarization of e e − + , initial beams, the radion mass m , the center of mass energy s . Based on the forward - backward asymmetry and the polarization of beams, the reaction can give observable cross-sections based on l l bb − + final state.
