Provided the formal and computational tools necessary to analyze pion-nucleus reactions [3,6,13,14].Wrote the program used to analyze virtually all of LAMPF pion-nucleus inelastic scattering data, clarified the role of nucleon-nucleon correlations in pion-nucleus double charge exchange reactions, and introduced what became known as the Miller-Spencer correlation function used in calculations of parity-violating nuclear matrix elements[13].
Originated and applied the cloudy bag model of hadrons [39,42,47,71]a model that explained the neutron electric form factor, the true nature of the Delta resonance, and the M1 radiative decays of mesons. Prediction [89] of the rate for pseudovector D meson to decay into a pseudoscalar D and a pion verified in a 2000 CLEO experiment.
Unveiled and computed the charge symmetry breaking part of the neutron-proton force that was subsequently observed in experiments at TRIUMF and IUCF[27,36,57,77,103,201] Introduced the quark-based definition (up-down quark mass difference) of charge symmetry[103]. Participated in the first experimental observation of the dd to alpha pi reaction[201]. The most recent work on charge symmetry breaking in pion production has recently been highlighted in Science News , Nature, CERN Courier , and Physics World . (If you are open-minded, check out also SciScoop.) It was also rated the #49 top science story in 2003 by Discover magazine.
Showed that the nuclear Drell Yan process could be used to probe the nuclear antiquark distribution[66,74]. A popular account is given in a page 3, LANL publication. Showed[204] how the chiral soliton model leads to nuclear saturation, explains the EMC effect and Drell-Yan data and predicts modifications of the nucleon electromagnetic form factor[209].
Our 1989 prediction[100] of the parity violating proton-proton total cross section verified in an 2001 experiment at TRIUMF.
Derived the connection between the strong coupling limit of QCD and nuclear physics[96]
Established the tools required to accurately compute the effects of color transparency[113,126,142]. Prediction [131] of the A-dependence of di-jet production in coherent pion-nucleus reactions made in 1993 was confirmed by experiments in 1999.
Applied chiral perturbation theory to explain the threshold production of neutral pions in proton-proton collisions [150,153].
Developed light front field theory for applications to nuclear physics[155,157,165,166]. Recovery of rotational invariance [162]
Used light front techniques to predict[151] a rapid decrease of the elastic electric form factor observed recently at Jlab, provide a qualitative explanation [188], describe all electromagnetic form factors [193], and introduce spin-dependent density operators to exhibit the non-spherical shape of the proton[200]. This work received a lot of attention in the popular press NY Times, May 6,2003, USA Today, Innovations, UWnews, Science Blog, Science a GoGo, Azono, The Hindu, RedNova, Brightsurf, Science Daily, transfer, Bible and Science, Butinage, Tregouet. Some technical details are to be found at our LFCBM site.
Showed that the charge density at the center of the neutron is negative [228], and that the magnetization density of the proton extends further than its charge density [232]. Showed that the non-spherical shape of the proton is measurable [231]. The work on the neutron is discussed in the Dec. 2007 issue (page 37) of Scientific American.
Originated a quantum mechanical treatment of HBT correlations that show that RHIC data was consistent with the presence of a chiral phase transition [211]. This work was discussed the Wall St. Journal (April 1, 2005) and in a Nature "News and Views" column by Wilczek Nature 435,152 (2005),
Explained features of protein-protein interaction networks using a statistical treatment of free energy [221,223] Proc. Nat'l Acad. Sci.103, 11527 (2006),
