This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The progress in lattice QCD, especially the capacity to calculate at ever lower quark masses, combined with modern techniques of chiral extrapolation, means that one can now determine the strange quark contribution to the vector form factors of the nucleon with remarkable precision. We review these recent landmark calculations and compare them with the most recent global analysis of the experimental situation using parity violating electron scattering.

Book excerpt: We explore the possibility of extrapolating state of the art lattice QCD calculations of nucleon form factors to the physical regime. We nd that the lattice results can be reproduced using the Light Front Cloudy Bag Model by letting its parameters be analytic functions of the quark mass. We then use the model to extend the lattice calculations to large values of Q2 of interest to current and planned experiments. These functions are also used to dene extrapolations to the physical value of the pion mass, thereby allowing us to study how the predicted zero in GE(Q2)/GM(Q2) varies as a function of quark mass.

Book excerpt: We explore the possibility of extrapolating state of the art lattice QCD calculations of nucleon form factors to the physical regime. We find that the lattice results can be reproduced using the Light Front Cloudy Bag Model and the Extended Gari-Krmpelmann Model by letting their parameters be analytic functions of the quark mass. We then use the models to extend the lattice calculations to large values of Q2 of interest to current and planned experiments. These functions for the first model are also used to define extrapolations to the physical value of the pion mass, thereby allowing us to study how the predicted zero in G{sub E}(Q2)/G{sub M}(Q2) varies as a function of quark mass.

Download or read book Strangeness and Charge Symmetry Violation in Nucleon Structure written by Phiala Elisabeth Shanahan and published by Springer. This book was released on 2016-05-11 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses two key topics: strangeness and charge symmetry violation (CSV) in the nucleon. It also provides a pedagogical introduction to chiral effective field theory tailored to the high-precision era of lattice quantum chromodynamics (QCD). Because the nucleon has zero net strangeness, strange observables give tremendous insight into the nature of the vacuum; they can only arise through quantum fluctuations in which strange–antistrange quark pairs are generated. As a result, the precise values of these quantities within QCD are important in physics arenas as diverse as precision tests of QCD, searches for physics beyond the Standard Model, and the interpretation of dark matter direct-detection experiments. Similarly, the precise knowledge of CSV observables has, with increasing experimental precision, become essential to the interpretation of many searches for physics beyond the Standard Model. In this thesis, the numerical lattice gauge theory approach to QCD is combined with the chiral perturbation theory formalism to determine strange and CSV quantities in a diverse range of observables including the octet baryon masses, sigma terms, electromagnetic form factors, and parton distribution functions. This thesis builds a comprehensive and coherent picture of the current status of understanding of strangeness and charge symmetry violation in the nucleon.

Available in PDF, EPUB and Kindle. Book excerpt: The second approach uses lattice QCD to perform a first-principles computation of the nucleon axial form factor. The Highly Improved Staggered Quark (HISQ) action is employed for both valence and sea quarks. The results presented in this dissertation are computed at physical pion mass for one lattice spacing. This work presents a computation of the axial form factor at zero momentum transfer, and forms the basis for a computation of the axial form factor momentum dependence with an extrapolation to the continuum limit and a full systematic error budget.

Book excerpt: Precision computation of hadronic physics with lattice QCD is becoming feasible. The last decade has seen precent-level calculations of many simple properties of mesons, and the last few years have seen calculations of baryon masses, including the nucleon mass, accurate to a few percent. As computational power increases and algorithms advance, the precise calculation of a variety of more demanding hadronic properties will become realistic. With this in mind, I discuss the current lattice QCD calculations of generalized parton distributions with an emphasis on the prospects for well-controlled calculations for these observables as well. I will do this by way of several examples: the pion and nucleon form factors and moments of the nucleon parton and generalized-parton distributions.
