Tests of Universality of Baryon Form Factors in Holographic QCD
A. Cherman, T. D. Cohen, M. Nielsen
We describe a new exact relation for large QCD for the long-distance behavior of baryon form factors in the chiral limit, satisfied by all 4D semi-classical chiral soliton mo…
The large-N(c) nuclear potential puzzle
A. V. Belitsky, T. D. Cohen
An analysis of the baryon-baryon potential from the point of view of large-N(c) QCD is performed. A comparison is made between the N(c)-scaling behavior directly obtained from an a…
Excited Heavy Baryons and Their Symmetries III: Phenomenology
Z. Aziza Baccouche, Chi-Keung Chow, Thomas D. Cohen +1
Phenomenological applications of an effective theory of low-lying excited states of charm and bottom isoscalar baryons are discussed at leading and next-to-leading order in the com…
Chiral multiplets versus parity doublets in highly excited baryons
T. D. Cohen, L. Ya. Glozman
It has recently been suggested that the parity doublet structure seen in the spectrum of highly excited baryons may be due to effective chiral restoration for these states. We argu…
Vanishing condensates and anomalously light Goldstone modes in medium
T. D. Cohen, W. Broniowski
We show that in a uniform medium, the vanishing of a particular condensate along with spontaneously broken symmetry imply the existence of an anomalously light pseudo-Goldstone mod…
Relations among Zero Momentum Correlators for Heavy-Light Systems in QCD
Xuemin Jin, Thomas D. Cohen
Relations connecting various zero momentum correlators of interpolating fields for pseudoscalar and scalar channel, containing one heavy and one light quark field, are derived from…
Unquenching the Rho Meson
Derek B. Leinweber, Thomas D. Cohen
Two-pion induced self-energy contributions to the -meson mass are examined in relation to the quenched approximation of QCD, where the physics associated with two-pion intermedi…
Response of nucleons to external probes in hedgehog models: II. General formalism
W. Broniowski, T. D. Cohen
Linear response theory for SU(2) hedgehog soliton models is developed.
Response of nucleons to external probes in hedgehog models: I. Electromagnetic polarizabilities
W. Broniowski, T. D. Cohen
Electromagnetic polarizabilities of the nucleon are analyzed in a hedgehog model with quark and meson degrees of freedom.
The structure of the pion and effective electroweak currents in soliton models of the nucleon
W. Broniowski, T. D. Cohen
Nonminimal substitution terms in electroweak currents are studied in effective chiral soliton models. It is found that the terms describing the structure of the pion lead to sizabl…
