Light isovector resonances in $\pi^- p \to \pi^-\pi^-\pi^+ p$ at 190 GeV/${\it c}$ / COMPASS Collaboration
We have performed the most comprehensive resonance-model fit of $\pi^-\pi^-\pi^+$ states using the results of our previously published partial-wave analysis (PWA) of a large data set of diffractive-dissociation events from the reaction $\pi^- + p \to \pi^-\pi^-\pi^+ + p_\text{recoil}$ with a 190 GeV/$c$ pion beam. The PWA results, which were obtained in 100 bins of three-pion mass, $0.5 < m_{3\pi} < 2.5$ GeV/$c^2$, and simultaneously in 11 bins of the reduced four-momentum transfer squared, $0.1 < t' < 1.0$ $($GeV$/c)^2$, are subjected to a resonance-model fit using Breit-Wigner amplitudes to simultaneously describe a subset of 14 selected waves using 11 isovector light-meson states with $J^{PC} = 0^{-+}$, $1^{++}$, $2^{++}$, $2^{-+}$, $4^{++}$, and spin-exotic $1^{-+}$ quantum numbers.

Amplitude analysis of four-body decays using a massively-parallel fitting framework / Hasse, C. (CERN ; Tech. U., Dortmund (main) ; Cincinnati U.) ; Albrecht, J. (Tech. U., Dortmund (main)) ; Alves, A.A. (Cincinnati U.) ; d'Argent, P. (Heidelberg U.) ; Evans, T.D. (Oxford U.) ; Rademacker, J. (Bristol U.) ; Sokoloff, M.D. (Cincinnati U.)
The GooFit Framework is designed to perform maximum-likelihood fits for arbitrary functions on various parallel back ends, for example a GPU. We present an extension to GooFit which adds the functionality to perform time-dependent amplitude analyses of pseudoscalar mesons decaying into four pseudoscalar final states. [...]

Discrete ambiguities in extracting weak phases from B decays / Dighe, Amol S. (Chicago U., EFI ; Chicago U.) ; Rosner, Jonathan L. (CERN ; Chicago U., EFI ; Chicago U.)
Phases of elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, as obtained using decays of $B$ mesons to $\pi~+ \pi~-$, $\pi~\pm K~\mp$, and $\pi~+ K~0$ or $\pi~- \overline{K}~0$, are shown to have a class of discrete ambiguities. In most cases these can be eliminated using other information on CKM phases..

Experimental tests of CPT symmetry and quantum mechanics at CPLEAR / CPLEAR Collaboration
We review a phenomenological parametrization of an open quantum-mechanical formalism for CPT violation in the neutral kaon system, and constrain the parameters using fits to recent CPLEAR data..

Precision tests of CPT symmetry and quantum mechanics in the neutral kaon system / Ellis, John R. (CERN) ; Lopez, Jorge L. (Texas A-M ; HARC, Woodlands) ; Mavromatos, N.E. (Annecy, LAPP) ; Nanopoulos, Dimitri V. (Texas A-M ; HARC, Woodlands)
We present a systematic phenomenological analysis of the tests of CPT symmetry that are possible within an {\em open} quantum-mechanical description of the neutral kaon system that is motivated by arguments based on quantum gravity and string theory. We develop a perturbative expansion in terms of the three small CPT-violating parameters admitted in this description, and provide expressions for a complete set of $K \rightarrow 2\pi, 3\pi$ and $\pi\ell\nu$ decay observables to second order in these small parameters.
