“…However, the effect of the vacuum final-state parton shower on φ was studied in Ref. [67] and it was demonstrated that the φ distributions obtained using the k T factorization and PYTHIA [68] with the final-state parton shower (FSR) agree in shape, while they differ slightly in normalization. When the FSR was neglected the two curves were almost on top of each other.…”

Jet quenching and effects of non-Gaussian transverse-momentum broadening on dijet observables

We study, at a qualitative level, production of jet pairs in ultrarelativistic nuclear collisions. We propose a new framework for combining k T factorization and a formalism for in-medium propagation of jet particles that takes into account stochastic transverse forces as well as medium-induced radiation. This approach allows to address dijet observables accounting for exact kinematics of the initial state. Using our framework, we provide a description of R AA data and study azimuthal decorrelations of the produced dijets. In particular, we find that the resulting dijet observables feature behavior deviating from that of jet pairs which undergo transverse-momentum broadening following the Gaussian distribution. We interpret this behavior as a consequence of dynamics encoded in the Blaizot-Dominguez-Mehtar-Tani-Iancu equation.

“…Subtracting the latter evolution contribution from eq. (5.3) and rearranging the terms, one obtains the following expressions for subtracted one-loop corrections to both scattering vertices: 5) which are also free from log r-divergences. By similar reasoning, one can obtain the subtracted one-loop correction to the scattering vertex with any regularization for rapidity divergences, including one proposed in JHEP08(2020)055 ref.…”

“…This conclusion is likely to generalize on a wide class of observables which are sensitive to the transverse momentum of incoming partons and absent in the LO of CPM. The ∆φ-spectrum of a dijet or multi-jet system at small values of ∆φ (away from back-to-back configuration) is a good example of such an observable [4][5][6].…”

“…These emissions generate a transverse momentum recoil, which greatly affects kinematic distributions of the final-state of interest, e.g. dior multi-jet system [4][5][6], pair of heavy-flavoured mesons [7,8] or heavy quarkonia [9]. Therefore, k T -factorization calculation serves as an interesting alternative to fixed-order calculations of such observables in Collinear Parton Model (CPM) or with conventional Parton Showers (PS) (see ref.…”

The perturbatively-stable scheme of Next-to-Leading order (NLO) calculations of cross-sections for multi-scale hard-processes in DISlike kinematics is developed in the framework of High-Energy Factorization. The evolution equation for unintegrated PDF, which resums log 1/z-corrections to the coefficient function in the Leading Logarithmic approximation together with a certain subset of Next-to-Leading Logarithmic and Nextto-Leading Power corrections, necessary for the perturbative stability of the formalism, is formulated and solved in the Doubly-Logarithmic approximation. An example of DISlike process, induced by the operator tr [G µν G µν ], which is sensitive to gluon PDF already in the LO, is studied. Moderate (O(20%)) NLO corrections to the inclusive structure function are found at small x B < 10 −4 , while for the p T-spectrum of a leading jet in the considered process, NLO corrections are small (< O(20%)) and LO of k T-factorization is a good approximation. The approach can be straightforwardly extended to the case of multi-scale hard processes in pp-collisions at high energies.

“…The parton densities x 1 f a/1 (x 1 , µ 2 ) are standard collinear parton densities and in our calculations we use CTEQ10NLO parton densities. The matrix elements |M g * g→g | 2 , |M g * q(q)→q(q) | 2 can be found in [28].…”

We revisit the calculation of rapidity dependence of the average transverse momentum p T of single inclusive jet production or particle in a p+p and p+P b collision, using the high energy factorization. We update previous predictions for the p T both in central and forward rapidity region using parton densities following from extended Balitsky-Kovchegov and Balitsky-Fadin-Kuraev-Lipatov evolution equations to account for corrections of higher orders as well as one obtained by Sudakov resummation. Furthermore, we demonstrate that in the midrapidity region the saturation based formalisms predict increase of the transversal momentum while in the forward rapidity region the p T (y) decreases.
