Measuring Arg( $V_{u b}$ ) in $B \to K π$

Frank Würthwein, Peter Gaidarev

It has previously been shown that a measurement of Arg $(V_{u b}) = γ$ can be obtained from a triangle construction using $B (B^{0} \to K^{+} π^{-})$ , $B (B^{0} ˉ \to K^{-} π^{+})$ , ${…

Aspects of Quenched Chiral Perturbation Theory for Matter Fields

Chi-Keung Chow

Three topics about the application of quenched chiral perturbation theory to matter fields are studied. It is proved that the hairpin axial current couplings in quenched chiral per…

Negative coupling instability and grandunified baryogenesis

Tomislav Prokopec

I review my recent work with Brian Greene and Thomas Roos. First I discuss the effect of a negative cross-coupling on the inflaton decay in two scalar field theories. Our main find…

Chiral Perturbation Theory for Tensor Mesons

Chi-Keung Chow, Soo-Jong Rey

Interactions of $a_{2}, K_{2}^{*}, f_{2}$ and $f_{2}^{'}$ tensor-mesons with low-energy $π, K, η, η^{'}$ pseudo-scalar mesons are constrained by chiral symmetry. We derive a chiral Lagrangian of t…

$1/ N_{c}$ Expansion for Excited Baryons

Dan Pirjol, Tung-Mow Yan

We derive consistency conditions which constrain the possible form of the strong couplings of the excited baryons to the pions. The consistency conditions follow from requiring the…

Quenched and Partially Quenched Chiral Perturbation Theory for Vector and Tensor Mesons

Chi-Keung Chow, Soo-Jong Rey

Quenched and partially quenched chiral perturbation theory for vector mesons is developed and is used to extract chiral loop correction to the $ρ$ meson mass. Connections to fully…

Inflaton Decay and Heavy Particle Production with Negative Coupling

Brian R. Greene, Tomislav Prokopec, Thomas G. Roos

We study the decay of the inflaton in a renormalizable two scalar theory. Since the dynamics of the system is dominated by states with large occupation numbers which admit a semicl…

Phenomenology of 3-Family Grand Unified String Models

Zurab Kakushadze, Gary Shiu, S. -H. Henry Tye +1

In the 3-family grand unified string models constructed so far, there is only one adjoint (and no higher dimensional representation) Higgs field in the grand unified gauge group. I…

Radiative Corrections to the Muonium Hyperfine Structure. II. The $α (Z α)^{2}$ Correction

M. Nio, T. Kinoshita

This is the second of a series of papers on the radiative corrections of order $α^{2} (Z α)$ , $α (Z α)^{2}$ , and various logarithmic terms of order $α^{4}$ , to the hyperfine structure of th…
