After a brief review of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) approach to Regge processes in QCD and supersymmetric gauge theories we propose strategy for calculating next-to-next-to-leading order corrections BFKL kernel. They can be obtained terms various cross sections Reggeized gluon interactions. The corresponding amplitudes calculated framework effective action high-energy scattering. In case $N=4$ supersymmetry it is also possible use Bern-Dixon-Smirnov ansatz. For this purpose...
In high-energy particle physics, the study of particle-particle correlations in proton-proton and heavy-ion collisions constitutes a pivotal frontier effort to understand fundamental dynamics strong force. To best our knowledge, we employ for first time Balitsky-Fadin-Kuraev-Lipatov implemented Monte Carlo code momentum space compute final-state collisions. Our present work aims investigate whether particular limit QCD can contribute long-range rapidity enigmatic ridge effect Published by...
We show that it is possible to describe the effective Pomeron intercept, determined from HERA deep inelastic scattering data at small values of Bjorken x, by using next-to-leading order Balitsky-Fadin-Kuraev-Lipatov evolution together with collinear improvements. To obtain a good description over whole range Q(2), we use non-Abelian physical renormalization scheme Brodsky-Lepage-Mackenzie optimal scale, combined parametrization running coupling in infrared region.
Real and virtual contributions to the quark-initiated forward jet vertex in QCD are calculated at next-to-leading logarithmic accuracy using Lipatov's effective action, valid high energy multi-Regge limit. A regularization of longitudinal divergencies is proposed which allows for determination observables. Agreement with previous results literature found.
We present a detailed description of the Q^2 and x dependence structure functions F2 FL as extracted from Deep Inelastic Scattering data at HERA in small Bjorken region. Making use collinearly-improved BFKL equation next-to-leading order treatment running coupling using non-Abelian physical renormalization together with BLM scale choice allows us to reach low values Q^2. also provide some predictions for future lepton-hadron colliders.
We define new observables sensitive to BFKL dynamics in the context of multijet production at large hadron collider (LHC). propose study inclusive three jets well separated rapidity from each other, with two them being very forward. show that tagging a third jet central region allows for strong test formalism. In particular, we have studied projections on azimuthal angles differential cross section which allow definition many different whose behavior when varying $p_t$ and is distinct signal...
We evaluate differential cross sections for production of four jets in multi-Regge kinematics at a hadron collider. The main focus lies on azimuthal angle dependences. As previous studies, the ratios correlation functions products cosines differences among tagged offer us cleanest quantities to compare with experimental data. calculations are based jet from single BFKL ladder convolution three Green where we always have two forward/backward final state. also demand tagging further more...
Motivated by the recent work of Brzemiński, Motyka, Sadzikowski and Stebel in [1], where forward Drell–Yan production is studied proton–proton collisions at LHC, we improve their calculation introducing an unintegrated gluon density obtained [2] from a fit to combined HERA data small values Bjorken x. This was calculated within BFKL formalism next-to-leading order with collinear corrections. We show that it generates good description cross section dependence on invariant mass lepton pair...
The subleading corrections to factorization theorems for soft bremsstrahlung in nonabelian gauge theories and gravity are investigated the case of a five point amplitude with four scalars. Building on recent results, we write action angular momentum operators scattering amplitudes as derivatives respect Mandelstam invariants uncover double copy structure contribution graviton amplitude, both leading term first correction. Using our approach, study Gribov’s theorem extended by Lipatov, find...
Recently, new observables in LHC inclusive events with three tagged jets were proposed. Here, we extend that proposal to four jets. The are characterized by one jet the forward direction, backward direction a large rapidity distance Y from first and two more central regions of detector. In our setup, non-tagged associated mini-jet multiplicity is present needs be accounted for inclusion BFKL gluon Green functions. projection cross section on azimuthal-angle components opens up opportunity...
We propose the study of new observables in LHC inclusive events with three tagged jets, one forward direction, backward direction and both well-separated rapidity from each other (Mueller-Navelet jets), together a third jet central regions rapidity. Since non-tagged associated mini-jet multiplicity is allowed, we argue that projecting cross sections on azimuthal-angle components can provide several distinct tests BFKL dynamics. Realistic kinematical cuts are introduced.
Ratios of azimuthal angle correlations between two jets produced at large rapidity separation are studied in the N=4 super Yang-Mills theory (MSYM). It is shown that these observables, which directly prove SL(2,C) symmetry present gauge theories Regge limit, exhibit an excellent perturbative convergence. They compared to those calculated QCD for different renormalization schemes concluding momentum-substraction (MOM) scheme with Brodsky-Lepage-Mackenzie (BLM) scale-fixing procedure captures...
We determine both real and virtual next-to-leading order corrections to the gluon induced forward jet vertex, from high energy effective action proposed by Lipatov. For these calculations we employ same regularization subtraction formalism developed in our previous work on quark-initiated vertex. find agreement with results literature.
Recently, a new family of observables consisting azimuthal-angle generalized ratios was proposed in kinematical setup that resembles the usual Mueller-Navelet jets but with an additional tagged jet central region rapidity. Nontagged minijet activity between three can affect significantly azimuthal angle orientation and is accounted for by introduction two Balitsky-Fadin-Kuraev- Lipatov (BFKL) gluon Green functions. Here, we calculate the, presumably, most relevant higher order corrections to...
We study ratios of azimuthal-angle distributions in Mueller-Navelet jets after imposing a rapidity veto constraint: the minijet radiation activity is restricted to only allow final-state partons separated at least distance $b$. It well-known that asymptotic growth with separation two tagged NLLA BFKL Green's function requires value $b \simeq {\cal O} (2)$ order avoid unphysical cross sections. further investigate this point from phenomenological view and work out those values $b$ which best...
Quantum properties of the state associated to gluon Green’s function in Balitsky-Fadin-Kuraev-Lipatov approach are studied using a discretization virtuality space. Considering coupling constant as imaginary, its density matrix corresponds pure for any energy. Nonlinear corrections due high densities modeled through suppression infrared modes Hamiltonian making it no longer Hermitian. This introduces quantum decoherence into evolution equation. When is real this leads unbounded normalization...
