Gell-Mann--Low scheme for the Standard Model
Grigorii B. Pivovarov
I describe a version of the Gell-Mann--Low scheme which is applicable to the Standard Model. First, I give a procedure for extracting input parameters of the theory from the Green'…
Naturalness and Renormalization Group in the Standard Model
Grigorii B. Pivovarov
I define a naturalness criterion formalizing the intuitive notion of naturalness discussed in the literature. After that, using as an example, I demonstrate that a theory may…
New Renormalization Group Equations and the Naturalness Problem
Grigorii Pivovarov
Looking for an observable manifestation of the so-called unnaturalness of scalar fields we introduce a seemingly new set of differential equations for connected Green functions. Th…
Asymptotic effects in jet production at high energies
V. B. Gavrilov, V. T. Kim, A. A. Krokhotin +2
Monte Carlo event simulation with BFKL evolution is discussed. We report current status of a Monte Carlo event generator ULYSSES with BFKL evolution implemented. The ULYSSES, based…
On Naturalness of Scalar Fields and Standard Model
Grigorii B. Pivovarov, Victor T. Kim
We discuss how naturalness predicts the scale of new physics. Two conditions on the scale are considered. The first is the more conservative condition due to Veltman (Acta Phys. Po…
The BFKL Pomeron within Physical Renormalization Schemes and Scales
V. S. Fadin, V. T. Kim, L. N. Lipatov +1
In this lecture the next-to-leading order (NLO) corrections to the QCD Pomeron intercept obtained from the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equation are discussed. It is shown…
High-Energy QCD Asymptotics of Photon-Photon Collisions
S. J. Brodsky, V. S. Fadin, V. T. Kim +2
The high-energy behaviour of the total cross section for highly virtual photons, as predicted by the BFKL equation at next-to-leading order (NLO) in QCD, is discussed. The NLO BFKL…
High-Energy Asymptotics of Photon--Photon Collisions in QCD
Stanley J. Brodsky, Victor S. Fadin, Victor T. Kim +2
The high-energy behaviour of the total cross section for highly virtual photons, as predicted by the BFKL equation at next-to-leading order (NLO) in QCD, is presented. The NLO BFKL…
The Next-to-Leading Dynamics of the BFKL Pomeron
Victor T. Kim, Lev N. Lipatov, Grigorii B. Pivovarov
The next-to-leading order (NLO) corrections to the BFKL equation in the BLM optimal scale setting are briefly discussed. A striking feature of the BLM approach is rather weak Q^2-d…
The Next-to-Leading BFKL Pomeron with Optimal Renormalization
Victor T. Kim, Lev N. Lipatov, Grigorii B. Pivovarov
The next-to-leading order (NLO) corrections to the BFKL equation in the BLM optimal scale setting are briefly discussed. A striking feature of the BLM approach is rather weak Q^2-d…
The QCD Pomeron with Optimal Renormalization
Stanley J. Brodsky, Victor S. Fadin, Victor T. Kim +2
It is shown that the next-to-leading order (NLO) corrections to the QCD Pomeron intercept obtained from the BFKL equation, when evaluated in non-Abelian physical renormalization sc…
Jet Production in Regge-Limit of QCD
Victor T. Kim, Grigorii B. Pivovarov
Current issues on jet production in hadron collisions for Regge-limit of QCD are briefly discussed.
A BFKL Pomeron Manifestation in Inclusive Single Jet Production at High-Energy Hadron Collisions
Victor T. Kim, Grigorii B. Pivovarov
A discrepancy between new data on inclusive single jet production at the Fermilab Tevatron and perturbative QCD is discussed. It is shown that the discrepancy may be accounted for…
A New Qualitative Prediction of the Parton Model for High Energy Hadron Collisions
Victor T. Kim, Grigorii B. Pivovarov, James P. Vary
Inclusive single jet production in hadron collisions is considered. It is shown that the QCD parton model predicts a nonmonotonic dependence of the inclusive cross section on the f…
Euclidean asymptotic expansions of Green functions of quantum fields (II) Combinatorics of the asymptotic operation
G. B. Pivovarov, F. V. Tkachov
The results of part I (hep-ph/9612284) are used to obtain full asymptotic expansions of Feynman diagrams renormalized within the MS-scheme in the regimes when some of the masses an…
Gauge Dependence of Four-Fermion QED Green Function and a Breakdown of Gauge Invariance in Atom-Like Bound State Calculations
Grigirii Pivovarov
We derive a relation between four-fermion QED Green functions of different covariant gauges which defines the gauge dependence completely. We use the derived gauge dependence to ch…

Victor T. Kim, Grigorii B. Pivovarov
New effective Feynman-like rules are defined for inclusive multijet cross sections in the multi-Regge regime. The solution of the BFKL equation is used as a starting point. The res…
BFKL QCD Pomeron in High Energy Hadron Collisions and Inclusive Dijet Production
