A New Paradigm for Hadronic Parity Nonconservation and its Experimental Implications
Susan Gardner, W. C. Haxton, Barry R. Holstein
For decades the primary experimental goal in studies of hadronic parity nonconservation (PNC) has been the isolation of the isovector weak nucleon-nucleon interaction, expected to…
Nuclear Physics without High-Momentum Potentials: Direct Construction of the Effective Interaction from Scattering Observables
Kenneth S. McElvain, W. C. Haxton
The standard approach to nuclear physics encodes phase shift information in an NN potential, then decodes that information in forming an effective interaction, appropriate to a low…
Hadronic Parity Violation
W. C. Haxton, B. R. Holstein
The history and phenomenology of hadronic parity nonconservation (PNC) is reviewed. We discuss the current status of the experimental tests and theory. We describe a re-analysis of…
Fundamental Symmetries and Conservation Laws
W. C. Haxton
I discuss recent progress in low-energy tests of symmetries and conservation laws, including parity nonconservation in atoms and nuclei, electric dipole moment tests of time-revers…
Nuclear Constraints on the Weak Nucleon-Nucleon Interaction
W. C. Haxton
I discuss the current status of efforts to constrain the strangeness-conserving weak hadronic interaction, which can be isolated in nuclear systems because of the associated parity…
Solar Neutrinos: Models, Observations, and New Opportunities
W. C. Haxton
I discuss the development and resolution of the solar neutrino problem, as well as opportunities now open to us to extend our knowledge of main-sequence stellar evolution and neutr…
Atomic Electric Dipole Moments: The Schiff Theorem and Its Corrections
C. -P. Liu, M. J. Ramsey-Musolf, W. C. Haxton +2
Searches for the permanent electric dipole moments (EDMs) of diamagnetic atoms provide powerful probes of CP-violating hadronic and semileptonic interactions. The theoretical inter…
Harmonic-Oscillator-Based Effective Theory
W. C. Haxton
I describe harmonic-oscillator-based effective theory (HOBET) and explore the extent to which the effects of excluded higher-energy oscillator shells can be represented by a contac…
Solar Hydrogen Burning and Neutrinos
W. C. Haxton, P. D. Parker, C. E. Rolfs
We summarize the current status of laboratory measurements of nuclear cross sections of the pp chain and CN cycle. We discuss the connections between such measurements, predictions…
Supernova Neutrino-Nucleus Physics and the r-process
W. C. Haxton
This talk reviews three inputs important to neutrino-induced nucleosynthesis in a supernova: 1) "standard" properties of the supernova neutrino flux, 2) effects of phenomena like n…
Perturbative Effective Theory in an Oscillator Basis?
W. C. Haxton, T. Luu
The effective interaction/operator problem in nuclear physics is believed to be highly nonperturbative, requiring extended high-momentum spaces for accurate solution. We trace this…
The Canonical Nuclear Many-Body Problem as an Effective Theory
W. C. Haxton, T. Luu
Recently it was argued that it might be possible treat the conventional nuclear structure problem -- nonrelativistic point nucleons interacting through a static and rather singular…
Anapole Moment and Other Constraints on the Strangeness Conserving Hadronic Weak Interaction
W. C. Haxton, C. -P. Liu, M. J. Ramsey-Musolf
Standard analyses of low-energy NN and nuclear parity-violating observables have been based on a pi-, rho-, and omega-exchange model capable of describing all five independent s-p…
Neutrino Effects in Nucleosynthesis
W. C. Haxton
The nucleosynthesis within a Type II supernova occurs in an intense neutrino flux. I discuss some of the effects associated with neutrino interactions, including direct synthesis i…
The Very Low Energy Solar Flux of Electron and Heavy-Flavor Neutrinos and Antineutrinos
W. C. Haxton, Wei Lin
We calculate the thermal flux of low-energy solar neutrinos and antineutrinos of all flavors arising from a variety of neutrino pair processes: Compton production (including plasmo…
Beyond the Shell Model: The Canonical Nuclear Many-Body Problem as an Effective Theory
W. C. Haxton, C. -L. Song
We describe a strategy for attacking the canonical nuclear structure problem ---bound-state properties of a system of point nucleons interacting via a two-body potential---which in…
Topics in Neutrino Astrophysics
W. C. Haxton
These lectures cover three topics in neutrino astrophysics. The solar neutrino problem is reviewed, with particular emphasis on the microphysics of the standard solar model, detect…
Fundamental Symmetries and Theory
W. C. Haxton
Nuclei are powerful laboratories for studying fundamental symmetries because they filter and enhance specific interactions. I discuss four examples --- hadronic parity violation, a…
Cross Section Uncertainties in the Gallium Neutrino Source Experiments
W. C. Haxton
The 51Cr neutrino source experiments play a unique role in testing overall operations of the GALLEX and SAGE solar neutrino experiments. Recently Hata and Haxton argued that the ex…
3He Transport and the Question of Nonstandard Solar Models
W. C. Haxton
I consider phenomenological changes in the standard solar model with the goal of testing recent claims that the solar neutrino puzzle requires new particle physics. The assumption…
He Transport in the Sun and the Solar Neutrino Problem
Andrew Cumming, W. C. Haxton
Recent solar neutrino experiments have shown that both B) and the neutrino flux ratio Be)/B) are substantially below their standard solar model values, leading so…
Salty Water Cerenkov Detectors
W. C. Haxton
The addition of certain solutes to a water Cerenkov detector will introduce new charge-current channels for the detection of s. The experimental conditions necessary to exploi…
