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.

Measurements of $\phi_s$ at the LHCb experiment / Cowan, Greig A. (Edinburgh U.) /LHCb Collaboration
These proceedings present the current status of measurements of the CP-violating phase $phi_s$ by the LHCb collaboration, reviewing the measurements in channels such as $B_s^0\to J/\psi\phi$, $B_s^0\to J/\psi \pi^+\pi^-$ and $B_s^0 \to \psi(2S)\phi$. The observation of the $B_s^0\to\eta_c\phi$ decay mode is presented for the first time, which can be used to measure $\phi_s$ with larger data samples that will be collected over the coming years by the LHCb experiment.

New limits on heavy neutrinos from Kaon experiments at CERN / Massri, Karim (CERN)
The NA48/2 and NA62-$R_K$ experiments at CERN collected large samples of charged kaon decays in 2003--2004 and 2007, respectively. These samples, collected with different trigger conditions, allow to search for both short and long-living heavy neutrinos produced in $K^{\pm}\to\mu^{\pm}N_4$ decays. [...]

Searches for Light Exotics at LHCb / Redi, Federico (Imperial Coll., London) /LHCb Collaboration
We report on the latest direct searches for light exotics at LHCb, conducted during Run I of LHC. This proceedings are divided into two sections, the first part will cover the search for the lepton number violating decay ${B}\rightarrow {\pi^{+}\mu^{-}\mu^{-}}$ while the second part will cover the search for a low mass dark boson in the decay $B^0 \rightarrow K^{*0}\chi$, with $\chi \rightarrow \mu^+\mu^-$ and $K^{*0} \rightarrow K^+\pi^-$.

Recent results from NA48/2 and NA62 experiments at CERN / Lurkin, Nicolas (Birmingham U.)
The NA48/2 and $\text{NA62}\text{-}{\text{R}_\text{K}}$ experiments at the CERN SPS collected a large sample of charged kaon decays in flight. $\text{NA62}\text{-}{\text{R}_\text{K}}$ was running in 2007-08 with a highly efficient minimum bias trigger for decays into electrons. [...]

Measurement of the $C\!P$ violation parameter $A_\Gamma$ in $D^0 \to K^+K^-$ and $D^0 \to \pi^+\pi^-$ decays / LHCb Collaboration
Asymmetries in the time-dependent rates of $D^0 \to K^+K^-$ and $D^0 \to \pi^+\pi^-$ decays are measured in a $pp$ collision data sample collected with the LHCb detector during LHC Run 1, corresponding to an integrated luminosity of $3\,\mathrm{fb}^{-1}$. The asymmetries in effective decay widths between $D^0$ and $\overline{D}^0$ decays, sensitive to indirect $CP$ violation, are measured to be $A_\Gamma(K^+ K^-) = (-0.30 \pm 0.32 \pm 0.10)\times 10^{-3}$ and $A_\Gamma(\pi^+\pi^-) = (0.46 \pm 0.58 \pm 0.12)\times 10^{-3}$, where the first uncertainty is statistical and the second systematic.

The $A_{1}$ meson produced at 63 and 94 GeV/c in the reaction $\pi^{-} p\to\pi^{-}\pi^{-}\pi^{+}p$ / Thompson, G (Oxford U.) /ACCMOR Collaboration
The results are presented of partial wave analyses of almost 600000 events from the reaction pi /sup -/p to pi /sup -/ pi /sup -/ pi /sup +/p at 63 and 94 GeV/c and with a higher momentum transfer trigger. The shape of the 1/sup +/S ( rho pi ) mass spectrum changes substantially as a function of t, and is not compatible with predictions of the Deck model. [...]

Mixing in the $D^0$ system : Results from collider experiments / Grothe, Monika (CERN)
Mixing in the D0 system may provide a sensitive probe for new physics beyond the Standard Model (SM) but has so far eluded experimental observation. The SM predictions are typically small (< 10^{-3}) for the mixing parameters x, y which, in the absence of charge-parity (CP) symmetry violation, measure the mass (x= Delta(m)/Gamma) and lifetime (y= Delta(Gamma)/2Gamma) difference of the CP eigenstates in the D0 system.
