Study of the process $e^+ e^- \to \omega\pi^0 $ with the KLOE detector
Using $\sim$ 600 pb$^{-1}$ collected with the KLOE detector at DA$\Phi$NE, we have studied the production cross section of $\pi^+\pi^-\pi^0\pi^0$ and $\pi^0\pi^0\gamma$ final states in $e^+ e^-$ collisions at center of mass energies between 1000 and 1030 MeV. By fitting the observed interference pattern around $M_\phi$ for both final states, we extract a measurement (preliminary) for the ratio $\Gamma(\omega\to\pi^0\gamma)/\Gamma(\omega\to\pi^+\pi^-\pi^0) = 0.0934\pm 0.0022$. Since these two final states represent the 98% of the $\omega$ decay channels, we use unitarity to derive $BR(\omega\to\pi^+\pi^-\pi^0)= (89.94\pm 0.23)%$ and $BR(\omega\to\pi^0\gamma) = (8.40\pm 0.19)%$. % Moreover, the parameters describing the \eeto\wpc reaction around $M_\phi$ are used to extract the branching fraction for the OZI and G-parity violating $\phi\to\omega\pi^0$ decay: $BR(\phi\to\omega\pi^0) = (5.63\pm 0.70)\times 10^{-5}$.

title: Measurement of the DAΦNE luminosity with the KLOE detector using large angle Bhabha scattering
abstract: We describe the method of measuring the integrated luminosity of the e+e- collider DAΦNE, the Frascati φ-factory. The measurement is done with the KLOE detector selecting large angle Bhabha scattering events and normalizing them to the effective cross section. The e+e-→e+e-(γ) cross section is calculated using different event generators which account for the $\mathcal{O}(\alpha)$ radiative initial and final state corrections, and the φ resonance contribution. The accuracy of the measurement is 0.6%, where 0.3% comes from systematic errors related to the event counting and 0.5% from theoretical evaluations of the cross section.

title: Search for New Phenomena with the Monojet and Missing Transverse Momentum Signature Using the ATLAS Detector in $\sqrt{s}=7$ TeV Proton-Proton Collisions
abstract: A search for new phenomena in events featuring a high energy jet and large missing transverse momentum in proton-proton collisions at root s = 7 TeV is presented using a dataset corresponding to an integrated luminosity of 33 pb(-1) recorded with the ATLAS detector at the Large Hadron Collider. The number of observed events is consistent with the Standard Model prediction. This result is interpreted in terms of limits on a model of Large Extra Dimensions.

title: Study of solar neutrinos with the 600 t liquid argon ICARUS detector
abstract: The ICARUS time projection chamber can yield sound information on 8 B solar neutrinos. Owing to the high-energy resolution and the good capability of event reconstruction it can make a contribution to our understanding of neutrino intensities and their energy spectrum. Moreover, the MSW oscillation probability for sterile and active neutrinos can be well studied because both elastic scattering by electrons and absorption reaction on argon nuclei can be measured independently. The main problem in detecting the low-energy neutrino interactions arises from the environmental radioactivity. In the present work we study by Monte Carlo simulation the topology and the rates of the events, induced by neutrinos and background neutrons, in a 470 t (fiducial mass) liquid-argon TPC detector. For neutrino interactions we use the standard solar model BP98 and the recent experimental confirmation of the shell model computation of absorption cross section. The noise is estimated from new data on natural neutron background, collected in the hall C of the Gran Sasso laboratory. It is confirmed that, with a relatively modest neutron shielding and particular off-line event triggers, the weight of spurious events can be made to have little influence on the ICARUS solar neutrino measurement. Indeed, we expect 6 (26) background events per year in the 212 (759) elastic scattering (absorption reaction) sample.

title: Bunch lengthening study in BEPC
abstract: The bunch lengthening in the Beijing Electron-Positron Collider (BEPC) is investigated systematically with streak camera and the method of beam spectrum analysis. Many available results are obtained from the measurement and the corresponding scaling law is summarized in the light of the existing theoretical explanation. Due to its importance for BEPC upgrades, the related parameters and effects of bunch lengthening are studied in details.

title: The studies of current dependent phenomena at the BEPC

title: BEAM INSTABILITY STUDIES IN THE BEPC
abstract: The Beijing Electron Positron Collider (BEPC) has been operated since 1987 for the experiment of high energy physics and synchrotron radiation application. About 25mA of a single bunch per beam for colliding is obtained at the energy of 1.55GeV, and over 120mA multi-bunch electron beam is reached at the energy of 2.2GeV in routine operation. Many current dependent phenomena have been observed and analysed during operation and machine studies for years. The bunch lengthening effect, the beam photoelectron instability, the dust effect and the beam ion instability are intensively studied in recent years.
