We develop threshold resummation for single-particle inclusive cross sections in hadron-hadron collisions to the level of next-to-next-to-leading logarithm, up to full matching with two-loop hard functions. We define and calculate all one-loop soft functions for all partonic channels. This enables us to separate the hard and soft functions at one loop. Along with these results, the one-loop finite parts of jet functions are used to check that the full soft, collinear and virtual corrections are reproduced to one loop for all partonic reactions. We exhibit these NLO results explicitly. NLO expansions of the resummed cross section match the exact NLO results extremely well numerically, and two loop expansions result in substantial corrections over many kinematic configurations. Explicit results are given in Mellin moment space, and a number of options for generating resummed cross sections are discussed.

“…In perturbative QCD, the fixed order predictions for the observables are often unreliable in certain regions of phase space due to the presence of large logarithms [23]. For example, at the hadron colliders, the inclusive observables like total cross section or invariant mass distribution of finial state colorless state and some differential distributions contain large logarithms which can spoil the reliability of fixed order results.…”

We present a detailed study on the infrared structure of N = 4 SYM and its connection to QCD. Calculation of collinear splitting functions helps to understand the structure and thus one can get infrared safe cross sections. We also demonstrate the factorization property that soft plus virtual part of the cross section satisfies and through factorization, we calculate soft distribution function up to third order in perturbation theory. We show that the soft distribution function is process independent that includes operators as well as external legs. In addition to this we compare our findings against the known results in QCD through principle of maximum transcendentality (PMT). We extend our analysis further for the case of three-point form factors involving stress tensor and find that it violates the PMT while comparing with the corresponding quantity in the standard model, observed for the first time at the level of form factor.

“…To achieve this, we exploit the Sudakov (KG) equation that the virtual part (form factor) of the cross section satisfy, renormalization group invariance, factorization theorem and use various three-loop results. We use the framework developed in [16,17,18,19,20] which describes resummation of soft gluons to all orders in QCD perturbation theory. In [17], it was shown that DIS cross section in the threshold limit factorizes into the square of ultraviolet (UV) renormalized form factor, soft plus jet (SJ) function and the mass factorization kernels.…”

We present the first result on the three-loop parton (quark/gluon) jet function in perturbative quantum chromodynamics using already known three-loop coefficient functions for deep-inelastic scattering via the exchange of a virtual photon that couples to quarks or a scalar that couples to gluons. While the gluon jet function is a brand new result emerging from this article, the result for the quark jet function provides an independent check to a more recent calculation. These jet functions being universal ingredients in the Soft-collinear effective theory framework, will play an important role in the phenomenological studies at the Large Hadron Collider, such as resummation of jet observables and also in N-jettiness subtraction method.
