Testing PT with the masses of the Nambu-Goldstone bosons
H. Leutwyler
The spontaneous breakdown of an approximate symmetry implies that the spectrum of the theory contains approximately massless particles. The hidden symmetry very strongly constrains…
The strong interactions
H. Leutwyler
Introductory section for the volume 50 years of Quantum Chromodynamics (edited by F. Gross and E. Klempt, to be published in Eur. Phys. J. C)
50 Years of Quantum Chromodynamics
Franz Gross, Eberhard Klempt, Stanley J. Brodsky +92
This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73…
Strange Hadron Spectroscopy with Secondary KL Beam in Hall D
KLF Collaboration, Moskov Amaryan, Mikhail Bashkanov +150
We propose to create a secondary beam of neutral kaons in Hall D at Jefferson Lab to be used with the GlueX experimental setup for strange hadron spectroscopy. The superior CEBAF e…
Sum rule for the Compton amplitude and implications for the proton-neutron mass difference
J. Gasser, H. Leutwyler, A. Rusetsky
The Cottingham formula expresses the leading contribution of the electromagnetic interaction to the proton-neutron mass difference as an integral over the forward Compton amplitude…
On the mass difference between proton and neutron
J. Gasser, H. Leutwyler, A. Rusetsky
The Cottingham formula expresses the electromagnetic part of the mass of a particle in terms of the virtual Compton scattering amplitude. At large photon momenta, this amplitude is…
