Thermodynamic Properties of Effective Chiral Lagrangians with BR Scaling

Chaejun Song, Dong-Pil Min, Mannque Rho

We show that effective chiral Lagrangians endowed with Brown-Rho scaling can be mapped to Landau Fermi-liquid fixed point theory in a way consistent with general constraints follow…

High-mass diffraction in the QCD dipole picture

A. Bialas, H. Navelet, R. Peschanski

Using the QCD dipole picture of the BFKL pomeron, the cross-section of single diffractive dissociation of virtual photons at high energy and large diffractively excited masses is c…

Is QCD at small x a string theory?

R. Peschanski

Using the dipole picture describing the limit of QCD at small and the conformal invariance properties of the BFKL kernel in transverse coordinate space, we show that th…

Selection rules at the quark-antiquark vertex of the QCD Pomeron

H. Navelet, R. Peschanski

We derive the full analytic expression for the QCD eikonal coupling of a quark-antiquark state to the exchanged gluon-gluon state in the BFKL formalism. The formula is valid for al…

Pion Light-Cone Wave Functions and Light-Front Quark Model

V. M. Belyaev, Mikkel B. Johnson

We discuss a relation between the light-front quark model and QCD. We argue that this model can be used for an evaluation of the light-cone wave functions for moderate values of "u…

Advanced Techniques for Multiparton Loop Calculations: A Minireview

Zvi Bern, Lance Dixon, David C. Dunbar +1

We present an overview of techniques developed in recent years for the efficient calculation of one-loop multiparton amplitudes, in particular those relying on unitarity and collin…

Parton Densities from Collider Data

David A. Kosower

Collider data can play an important role in determining the parton distribution functions of the nucleon. I outline a formalism which makes it possible to use next-to-leading order…

Fluctuations In ``BR-Scaled'' Chiral Lagrangians

Chaejun Song, G. E. Brown, Dong-Pil Min +1

We develop arguments for "mapping" the effective chiral Lagrangian whose parameters are given by "BR scaling" to a Landau Fermi-liquid fixed-point theory for nuclear matter in desc…

Dual Shapiro-Virasoro amplitudes in the QCD dipole picture

R. Peschanski

Using the QCD dipole picture of BFKL dynamics and the conformal invariance properties of the BFKL kernel in transverse coordinate space, we show that the 1--to--p dipole densities…

Color Anomaly and Flavor-Singlet Axial Charge of the Proton in the Chiral Bag: The Cheshire Cat Revisited

Mannque Rho, Vicente Vento

Quantum effects inside the chiral bag induce a color anomaly which requires a compensating surface term to prevent breakdown of color gauge invariance. We show that the presence of…

Conformal Invariance and the exact solution of BFKL equations

H. Navelet, R. Peschanski

The conformal invariance properties of the QCD Pomeron in the transverse plane allow us to give an explicit analytical expression for the solution of the BFKL equations both in the…

Distribution of valence quarks and light-cone QCD sum rules

V. M. Belyaev, Mikkel B. Johnson

A method for calculating the pion structure function directly in terms of light-cone wave functions is suggested. Taking twist-2 and twist-4 pion light-cone wave functions into acc…

A New State Of Hadronic Matter At High Density

Kurt Langfeld, Hugo Reinhardt, Mannque Rho

We propose in this article that if the chemical potential exceeds a critical value in dense hadronic medium, a first-order phase transition to a new state of matter with Lorentz sy…

A Note on the QCD Vacuum Tensor Susceptibility

V. M. Belyaev, A. Oganesian

We consider the procedure of determination of induced quark condensates in the QCD sum rule approach. It is noted that the previous estimations of this value were very rough. It is…
