چکیده
We study the transverse spin structure of squeezed limit three-point energy correlator, $\langle \mathcal{E}(\vec n_1) n_2) n_3) \rangle$. To describe its all orders perturbative behavior, we develop light-ray operator product expansion (OPE) in QCD. At leading twist iterated OPE $\mathcal{E}(\vec n_i)$ operators closes onto $\mathbb{O}^{[J]}(\vec n)$ with $J$, and $j=0,2$. compute n_2)$, \mathbb{O}^{[J]}(\vec $ $\mathbb{O}^{[J_1]}(\vec \mathbb{O}^{[J_2]}(\vec OPEs as analytic functions which allows for description arbitrary limits $N$-point correlators use these results $J=3$ to reproduce well resum singular both quark gluon jets, including contributions, required phenomenological applications. Finally, briefly comment on at higher twists, show that highest contributions are universal between descendants spin-2 operator, allowing their resummation into a simple two-dimensional Euclidean conformal block. Due general applicability our correlation flow operators, anticipate they can be widely applied improving understanding jet substructure LHC.

Gluons, Quarks, and the Transition from Nonperturbative to Perturbative Qcd
Lattice-based investigations of two fundamental QCD quantities are described, namely the gluon and quark propagators in Landau gauge. We have studied the Landau gauge gluon propagator using a variety of lattices with spacings from a = 0.17 to 0.41 fm to explore finite volume and discretization effects. We also introduce the general method of “tree-level correction” to minimize the effect of lat...
متن کاملAre Two Gluons the QCD Pomeron?
Collider experiments have recently measured the production cross section of hard jets separated by a rapidity gap as a function of transverse momentum and gap size. We show that these measurements reveal the relative frequencies for the production of rapidity gaps in quark-quark, quark-gluon and gluon-gluon interactions. The results are at variance with the idea that the exchange of 2 gluons is...
متن کاملSe p 19 95 CONSTITUENT GLUONS FROM QCD
The notion of constituent gluon is introduced as a gluon propagating in the vacuum background field. The Hamiltonian approach for a system containing such gluon and a q ¯ qg pair is formulated, and the masses of lowest q ¯ qg hybrids are estimated. In the QCD–motivated constituent models not only quarks but also glu-ons should be confined, so that the states containing constituent glue should e...
متن کاملSoft gluons and superleading logarithms in QCD
After a brief introduction to the physics of soft gluons in QCD we present a surprising prediction. Dijet production in hadron-hadron collisions provides the paradigm, i.e. h1 + h2 → jj + X. In particular, we look at the case where there is a restriction placed on the emission of any further jets in the region in between the primary (highest pT ) dijets. Logarithms in the ratio of the jet scale...
متن کاملOPE of the energy-momentum tensor correlator in massless QCD
Abstract: We analytically calculate higher order corrections to coefficient functions of the operator product expansion (OPE) for the Euclidean correlator of two energy-momentum tensors in massless QCD. These are the three-loop contribution to the coefficient C0 in front of the unity operator O0 = 1 and the one and two-loop contributions to the coefficient C1 in front of the gluon “condensate” ...
