Coupled channel analysis of $\pi^+ \pi^ -\pi^0$, $K^+ K^- \pi^0$ and $K^{\pm} K^0_S \pi^{\mp}$ from $\bar p p$ annihilation at rest in hydrogen targets at three densities / Bargiotti, M (Bologna U. ; INFN, Bologna) ; Bertin, A (Bologna U. ; INFN, Bologna) ; Bruschi, M (Bologna U. ; INFN, Bologna) ; Capponi, M (Bologna U. ; INFN, Bologna) ; De Castro, S (Bologna U. ; INFN, Bologna) ; Fabbri, L (Bologna U. ; INFN, Bologna) ; Faccioli, P (Bologna U. ; INFN, Bologna) ; Galli, D (Bologna U. ; INFN, Bologna) ; Giacobbe, B (Bologna U. ; INFN, Bologna) ; Marconi, U (Bologna U. ; INFN, Bologna) et al. /OBELIX
The $\pi^+ \pi^ -\pi^0$, $K^+ K^- \pi^0$ and $K^\pm K^0 \pi^\mp$ final states produced by $\bar p p$ annihilation at rest at three different hydrogen target densities have been analyzed in the frame of a coupled channel analysis together with $\pi \pi$, $\pi K$ and $K \bar K$ scattering data. The percentages of the different partial waves, the branching ratios and the parameters (masses, widths, $\pi \pi$ and $K \bar K$ partial widths) of all the involved resonances ($J^P = 0^+, 1^-, 2^+$) have been measured.

Time correlated events due to cosmic muons from extensive air showers have been detected by means of telescope pairs of the EEE (Extreme Energy Events) Project array. The coincidence rate, properly normalized for detector acceptance, efficiency and altitude location, has been extracted as a function of the relative distance between the telescopes. [...]

New data on OZI rule violation in $\overline{P}P$ annihilation at rest / OBELIX Collaboration
The results of a measurement of the ratio R =3D Y(phi pi+ pi-) / Y(omega = pi+ pi-) for antiproton annihilation at rest in a gaseous and in a liquid hydrogen target are presented. It was found that the value of this ratio increases with the decreasing of the dipion mass, which demonstrates the difference in the phi and omega production mechanisms. [...]

Resonance Production and $\pi\pi$ S-wave in $\pi^- + p \rightarrow \pi^- \pi^- \pi^+ + p_{recoil}$ at 190 GeV/c / COMPASS collaboration
The COMPASS collaboration has collected the currently largest data set on diffractively produced $\pi^-\pi^-\pi^+$ final states using a negative pion beam of 190 GeV/c momentum impinging on a stationary proton target. This data set allows for a systematic partial-wave analysis in 100 bins of three-pion mass, $0.5 < m_{3\pi} < 2.5$ GeV/c$^2$ , and in 11 bins of the reduced four-momentum transfer squared, $0.1 < t < 1.0$ (GeV/c)$^2$ .

Modern experiments search for extremely rare processes hidden in much larger background levels. As the experiment complexity, the accelerator backgrounds and luminosity increase we need increasingly exclusive selections to efficiently select the rare events inside the huge background. [...]

Neutron-proton coincidences from Non-Mesonic Weak Decay of p-shell Lambda-hypernuclei and determination of the two-nucleon induced process / Agnello, M (INFN, Turin ; Turin Polytechnic) ; Benussi, L (Frascati) ; Bertani, M (Frascati) ; Bhang, H C (Seoul Natl.

The decay of Lambda-hypernuclei without pi emission, known as Non-Mesonic Weak Decay (NMWD), gives an effective tool to investigate Delta S = 1 four-baryon interactions. It was theoretically suggested that the two-nucleon induced mechanism could play a substantial role in reproducing the observed NMWD decay rates and nucleon spectra, but at present no direct evidence of such a mechanism has been obtained.

Longitudinal double spin asymmetries in single hadron quasi-real photoproduction at high $p_T$ / COMPASS Collaboration
We measured the longitudinal double spin asymmetries $A_{LL}$ for single hadron muo-production off protons and deuterons at photon virtuality $Q^2$ < 1(GeV/$\it c$)$^2$ for transverse hadron momenta $p_T$ in the range 0.7 GeV/$\it c$ to 4 GeV/$\it c$ . They were determined using COMPASS data taken with a polarised muon beam of 160 GeV/$\it c$ or 200 GeV/$\it c$ impinging on polarised $\mathrm{{}^6LiD}$ or $\mathrm{NH_3}$ targets. [...]

Measurements of the reaction $pp \to \phi \eta$ of antiproton annihilation at rest at three hydrogen target densities / OBELIX Collaboration
The proton-antiproton annihilation at rest into the $\phi\eta$ final state was measured for three different target densities: liquid hydrogen, gaseous hydrogen at NTP and at a low pressure of 5 mbar. The yield of this reaction in the liquid hydrogen target is smaller than in the low-pressure gas target. [...]

Measurement of the radiative $K_{e3}$ branching ratio / NA48 Collaboration
We present a measurement of the relative branching ratio of the decay $K^{0} \to \pi^{\pm}e^{\pm}\nu\gamma (K_{e3\gamma})$ with respect to $K^{0} \to \pi^{\pm} e^{\pm}\nu(K_{e3} + K_{e3\gamma})$ decay. The result is based on observation of 19 000 $K_{e3\gamma}$ and $5.6 \times 10^{6} K_{e3}$ decays. [...]
