Family Symmetry and Neutrino Mixing

John K. Elwood, Nikolaos Irges, Pierre Ramond

The observed quark hierarchies suggest a simple family symmetry. Generalized to leptons through grand-unified quantum numbers, it produces a neutrino mixing matrix with order-one ν…

Transverse Spin Dependent Drell Yan in QCD to $O (α_{s}^{2})$ at Large $p_{T}$ (I). Virtual Corrections and Methods for the Real Emissions

Sanghyeon Chang, Claudio Coriano, John K. Elwood

We investigate the role of the transverse spin dependence in Drell Yan lepton pair production to NLO in QCD at parton level. In our analysis we deal with the large $p_{T}$ distributi…

A Model of Yukawa Hierarchies

John K. Elwood, Nikolaos Irges, Pierre Ramond

We present a model for the observed hierarchies among the Yukawa couplings of the standard model in the context of an effective low energy theory with an anomalous U(1) symmetry. T…

Exotic leptoquarks from superstring derived models

John K. Elwood, Alon E. Faraggi

The H1 and ZEUS collaborations have recently reported a significant excess of events at high $Q^{2}$ in positron-proton collisions. While there exists insufficient data to conclusive…

Excited Charmed Baryon Decays and Their Implications for Fragmentation Parameters

John K. Elwood

The production of the excited charmed baryon doublet $Λ_{c}^{*}$ via fragmentation is studied. An analysis of the subsequent hadronic decays of the doublet within the framework of heav…

Final State Interactions and CP Violation in $K_{L} \to π^{+} π^{-} e^{+} e^{-}$

John K. Elwood, Mark B. Wise, Martin J. Savage +1

Using chiral perturbation theory we calculate the imaginary parts of the $K_{L} \to π^{+} π^{-} e^{+} e^{-}$ form factors that arise from $π π \to π^{+} π^{-}$ and $ππ\rightarrow π…

K_L to π^+ π^- e^+ e^-

John K. Elwood, Mark B. Wise, Martin J. Savage

We calculate all of the form factors for the one-photon, $K_{L} \to π^{+} π^{-} γ^{*} \to π^{+} π^{-} e^{+} e^{-}$ contribution to the $K_{L} \to π^{+} π^{-} e^{+} e^{-}$ decay amplitu…
