Models of Isospin Breaking in the Pion Form Factor: Consequences for the Determination of Pi_{ρω}(m_rho^2) and (g-2)_mu/2
C. E. Wolfe, K. Maltman
We study the implications of several recent high-precision measurements of the pion form factor in the region of the rho-omega interference "shoulder" for (i) the extraction of the…
Constraints on the I=1 hadronic tau decay and e^+e^- --> hadrons data sets and implications for (g-2)_mu
Kim Maltman
Sum rule tests are performed on the spectral data for (i) flavor 'ud' vector- current-induced hadronic tau decays and (ii) e^+ e^- hadroproduction, in the region below s~3-4 GeV^2,…
Issues in the Extraction of m_s and V_us from Hadronic Tau Decay Data
K. Maltman
Various complications encountered in the process of attempting to extract the basic Standard Model parameters, m_s and V_us, from hadronic tau decay data are discussed. Preliminary…
QCD Condensates for the Light Quark V-A Correlator
V. Cirigliano, E. Golowich, K. Maltman
We use the procedure of pinched-weight Finite Energy Sum Rules (pFESR) to determine the OPE coefficients a_6, ...,a_16 of the flavor ud V-A correlator in terms of existing hadronic…
The Strong Isospin-Breaking Correction for the Gluonic Penguin Contribution to epsilon'/epsilon at Next-to-Leading Order in the Chiral Expansion
C. E. Wolfe, K. Maltman
The strong isospin-breaking correction, Omega_{st}, which appears in estimates of the Standard Model value for the direct CP-violating ratio epsilon'/epsilon, is evaluated to next-…
Strong Isospin Breaking in CP-even and CP-odd K -> pi pi Decays
C. E. Wolfe, K. Maltman
Complete next-to-leading (chiral) order (NLO) expressions for the strong isospin-breaking (IB) contributions in K -> pi pi are used to discuss (1) for CP-even, the impact on the ma…
O(m_d-m_u) Effects in CP-even and CP-odd K-->pi pi Decays
K. Maltman, C. E. Wolfe
Strong isospin-breaking (IB) effects in CP-even and CP-odd K-->pi pi decays are computed to next-to-leading order (NLO) in the chiral expansion. The impact of these corrections on…
Isospin Breaking in the Extraction of Isovector and Isoscalar Spectral Functions from e^+e^- --> hadrons
K. Maltman, C. E. Wolfe
A finite energy sum rule (FESR) analysis of the isospin-breaking vector current correlator <0|T(V^3_μV^8_ν)|0> is used to determine the isospin-breaking electromagnetic (EM) decay…
Strong Isospin-Breaking Effects in K-->pi pi at Next-to-Leading Order in the Chiral Expansion
Carl E. Wolfe, Kim Maltman
Strong isospin-breaking (IB) contributions to both the octet and 27-plet weak K-->2 pi transitions are evaluated at next-to-leading order (NLO) in the chiral expansion. NLO contrib…
Constraints on Hadronic Spectral Functions From Continuous Families of Finite Energy Sum Rules
K. Maltman
Hadronic tau decay data is used to study the reliability of various finite energy sum rules (FESR's). For intermediate scales (of order 2-3 GeV^2), those FESR's with weights s^k ar…
