Collective Perspective on Advances in Dyson-Schwinger Equation QCD
(Iop Publishing Ltd, 2012-07-01)
We survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson-Schwinger equations,addressing the following aspects: confinement and dynamical chiral symmetry breaking; the hadron spectrum; ...
Mapping of composite hadrons into elementary hadrons and effective hadronic Hamiltonians
(Academic Press Inc., 1998-09-01)
A mapping technique is used to derive in the context of constituent quark models effective Hamiltonians that involve explicit hadron degrees of freedom. The technique is based on the ideas of mapping between physical and ...
Field-theoretic approach for systems of composite hadrons
(1996-12-01)
Systems containing simultaneously hadrons and their constituents are most easily described by treating composite hadron field operators on the same kinematical footing as the constituent ones. Introduction of a unitary ...
Double Higgs production and quadratic divergence cancellation in little Higgs models with T-parity
(2006-05-01)
We analyze double Higgs boson production at the Large Hadron Collider in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that cause the cancellation of ...
Hadron plus photon production in polarized hadronic collisions at next-to-leading order accuracy
(American Physical Society, 2011-04)
We compute the next-to-leading order QCD corrections to the polarized (and unpolarized) cross sections for the production of a hadron accompanied by an opposite-side prompt photon. This process, being studied at RHIC, ...
Chiral aspects of hadron structure
(Elsevier B.V., 2000-05-18)
Chiral loop corrections for hadronic properties are considered in a constituent quark model. It is emphasized that the correct implementation of such corrections requires a sum over intermediate hadronic states. The leading ...
Chiral corrections in hadron spectroscopy
(1999-12-01)
We show that the implementation of chiral symmetry in recent studies of the hadron spectrum in the context of the constituent quark model is inconsistent with chiral perturbation theory. In particular, we show that the ...
Hadron mass spectrum and the shear viscosity to entropy density ratio of hot hadronic matter
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
Lattice calculations of the QCD trace anomaly at temperatures T < 160 MeV have been shown to match hadron resonance gas model calculations, which include an exponentially rising hadron mass spectrum. In this paper we ...
The correlation matrix of Higgs rates at the LHC
(2016-11-01)
The imperfect knowledge of the Higgs boson decay rates and cross sections at the LHC constitutes a critical systematic uncertainty in the study of the Higgs boson properties. We show that the full covariance matrix between ...
Identifying Multiquark Hadrons from Heavy Ion Collisions
(AMER PHYSICAL SOC, 2011)
Identifying hadronic molecular states and/or hadrons with multiquark components either with or without exotic quantum numbers is a long-standing challenge in hadronic physics. We suggest that studying the production of ...
