Abstract: We have studied the vector to pseudoscalar conversion decay ϕ→ηe+e−, with η→π0π0π0, with the KLOE detector at DAΦNE. The data set of 1.7 fb−1 of e+e− collisions at s∼Mϕ contains a clear conversion decay signal of ∼31,000 events from which we measured a value of BR(ϕ→ηe+e−)=(1.075±0.007±0.038)×10−4. The same sample is used to determine the transition form factor by a fit to the e+e− invariant mass spectrum, obtaining bϕη=(1.28±0.10−0.08+0.09) GeV−2, that improves by a factor of five the precision of the previous measurement and is in good agreement with VMD expectations.

Abstract: We have searched for a light vector boson $U$, the possible carrier of a "dark force", with the KLOE detector at the DA$\Phi$NE \epm\ collider, motivated by astrophysical evidence for the presence of dark matter in the universe. Using \epm\ collisions collected with an integrated luminosity of $239.3$~pb$^{-1}$, we look for a dimuon mass peak in the reaction \epm\to$\mu^+ \mu^-$\gam, corresponding to the decay $U\to\mu^+\mu^-$. We find no evidence for a $U$ vector boson signal. We set a 90\% CL upper limit for the mixing parameter squared between the photon and the $U$ boson of 1.6$\times$10$^{-5}$ to 8.6$\times$10$^{-7}$ for the mass region $520, Comment: 12 pages, 7 figures, version accepted for publication in Physics Letters B

Abstract: The muon anomalous magnetic moment is one of the most precisely measured quantities in particle physics and a persistent discrepancy of about $3 \sigma$ between standard model (SM) prediction and the experimental measurement has been observed. The leading order contribution $a_{\mu }^{hlo}$ is actually the main source of uncertainty in the theoretical evaluation of the muon anomaly. It is obtained by a dispersion integral using the precision measurement of hadronic cross section. The KLOE experiment at the DAΦNE $\phi$ −factory in Frascati was the first to exploit Initial State Radiation (ISR) processes to obtain the $e^{+}e^{-}\rightarrow \pi ^{+}\pi ^{-}\left ( \gamma \right )$ cross section below 1 GeV, that accounts for most (70%) of the leading order contribution to the muon anomaly. In year 2005 and 2008 the KLOE-collaboration has published two measurements of the $\pi ^{+}\pi ^{-}$ cross section with the photon in the initial state emitted at small angle, and an independent measurement with the photon emitted at large angle was finalized in year 2011. These measurements were normalized using luminosity from Bhabha. In the last years, a new analysis of KLOE data has been performed for obtaining the pion form factor directly from the bin-by-bin $\pi ^{+}\pi ^{-}\gamma$ to $\mu ^{+}\mu ^{-}\gamma$ ratio. We present the results of this new measurement, showing the comparison with our previous measurements, and its impact on the hadronic contribution to the muon anomaly.

Abstract: We present new data for angular distributions and on the cross section ratio of the $p + d \rightarrow ^{3}He + \it{\eta}$ reaction at excess energies of $\it{Q}$ = 48.8 MeV and $\it{Q}$ = 59.8 MeV. The data have been obtained at the WASA-at-COSY experiment (Forschungszentrum Jülich) using a proton beam and a deuterium pellet target. While the shape of obtained angular distributions show only a slow variation with the energy, the new results indicate a distinct and unexpected total cross section fluctuation between $\it{Q}$ = 20 MeV and $\it{Q}$ = 60 MeV, which might indicate the variation of the production mechanism within this energy interval.

Abstract: Charge symmetry breaking (CSB) observables are a suitable experimental tool to examine effects induced by quark masses on the nuclear level. Previous high precision data from TRIUMF and IUCF are currently used to develop a consistent description of CSB within the framework of chiral perturbation theory. In this work the experimental studies on the reaction dd\rightarrow $^{4}He\pi ^{0}$ have been extended towards higher excess energies in order to provide information on the contribution of p-waves in the final state. For this, an exclusive measurement has been carried out at a beam momentum of $p_{d}=1.2$ GeV/c using the WASA-at-COSY facility. The total cross section amounts to $\sigma _{tot} = (118 \pm 18_{stat} \pm 13_{sys} \pm 8_{ext}) pb$ and first data on the differential cross section are consistent with s-wave pion production.

Abstract: Neutral kaons from meson decays are produced in pairs, which offers the possibility to select pure kaon beams: the detection of a Ks (KL) tags the presence of a KL (Ks), the same holds for charged kaons. This allows to perform precise measurement of kaon properties. Additionally, these neutral kaon pairs are produced in a pure quantum state (JPC = 1−−), which allows to investigate CP and CPT symmetries via quantum interference effects, as well as the basic principles of quantum mechanics. Introduction to kaon interferometry and the results on the decoherence parameter and CPT test obtained by the KLOE experiment at the DAΦNE e+e− collider will be presented together with prospects for KLOE-2 project.

Abstract: An exclusive measurement of the dd\rightarrow $^{3}Hen\pi^{0}$ eaction was carried out at a beam momentum of $p_{d}$=1.2 GeV/c using the WASA-at-COSY facility. Information on the total cross section as well as differential distributions was obtained. The data are described by a phenomenological approach based on a combination of a quasifree model and a partial wave expansion for the three-body reaction. The total cross section is found to be $\sigma _{tot}= \left ( 2.89\pm 0.01_{stat}\pm 0.06_{sys}\pm 0.29_{norm} \right )\mu b$. The contribution of the quasifree processes (with the beam or target neutron being a spectator) accounts for 38% of the total cross section and dominates the differential distributions in specific regions of phase space. The remaining part of the cross section can be described by a partial wave decomposition indicating the significance of p-wave contributions in the final state.

Abstract: We have carried out a new direct search for the CP violating decay $K_{S}\rightarrow 3\pi ^{0}$ with $1.7 fb^{-1}$ of $e^{+}e^{-}$ collisions collected by the KLOE detector at the $\phi$ -factory DA$\Phi$ NE. We have searched for this decay in a sample of about $5.9 \times 10^{8} K_{S}K_{L}$ events tagging the $K_{S}$ by means of the $K_{L}$ interaction in the calorimeter and requiring six prompt photons. With respect to our previous search, the analysis has been improved by increasing of a factor four the tagged sample and by a more effective background rejection of fake $K_{S}$ tags and spurious clusters. We find no candidates in data and simulated background samples, while we expect 0.12 standard model events. Normalizing to the number of $K_{S}\rightarrow 2\pi ^{0}$ events in the same sample, we set the upper limit on $BR\left ( K_{S}\rightarrow 3\pi^{0} \right )\leqslant 2.6 \times 10^{-8}$ at 90% C.L., five times lower than the previous limit. We also set the upper limit on the $\eta _{000}$ parameter, $\mid \eta _{000}\mid\leqslant 0.0088$ at 90% C.L., improving by a factor two the latest direct measurement.

Abstract: Exclusive measurements of the quasifree $pn\rightarrow pp\pi ^{0}\pi ^{-}$ reaction have been performed by means of pd collisions at $T_{p}$= 1.2 GeV using the wide angle shower apparatus (WASA) detector setup at the cooler synchrotron COSY (Institut für Kernphysik, Jülich). Total and differential cross sections have been obtained covering the energy region $\sqrt{8}=\left ( 2.35-2.46 \right )$ GeV, which includes the region of the ABC effect and its associated resonance structure. No ABC effect, i.e., low-mass enhancement is found in the $\pi ^{0}\pi ^{-}$ -invariant mass spectrum, in agreement with the constraint from Bose statistics that the isovector pion pair can not be in relative s wave. At the upper end of the covered energy region t-channel processes for Roper, $\Delta \left ( 1600 \right )$ and $\Delta \Delta$ excitations provide a reasonable description of the data, but at low energies the measured cross sections are much larger than predicted by such processes. Adding a resonance amplitude for the resonance at m=2.37 GeV with $\Gamma$ =70 MeV and $I\left ( J^{P} \right )=0\left ( 3^{+} \right )$ observed recently in $pn\rightarrow d\pi ^{0}\pi ^{0}$ and $pn\rightarrow d\pi ^{+}\pi ^{-}$ reactions leads to an agreement with the data also at low energies.

Abstract: Neutral kaons produced in correlated pairs at a phi-factory offer unique possibilities to perform fundamental tests of CPT invariance, as well as of the basic principles of quantum mechanics. The analysis of the data collected by the KLOE experiment at DAFNE is still ongoing with the aim of improving previous results and limits on several parameters describing CPT violation and decoherence. Ancillary measurements like the regeneration cross section on the beam pipe materials are also in progress and will be very useful to reduce the systematic uncertainties. Prospects on improvements at the KLOE-2 experiment, aiming at an increase of the integrated luminosity of about a factor of ten with an upgraded detector, will be also discussed., Comment: 8 pages, 6 figures

Abstract: An exclusive measurement of the decay $\eta \rightarrow \pi^{+} \pi^{-} \gamma$ has been performed at the WASA facility at COSY. The $\eta$ mesons were produced in the fusion reaction $pd \rightarrow ^{3}He X$ at a proton beam momentum of 1.7 GeV/c. Efficiency corrected differential distributions have been extracted based on 13 960 $\pm$ 140 events after background subtraction. The measured pion angular distribution is consistent with a relative p-wave of the two-pion system, whereas the measured photon energy spectrum was found at variance with the simplest gauge invariant matrix element of $\eta \rightarrow \pi^{+} \pi^{-} \gamma$. A parameterization of the data can be achieved by the additional inclusion of the empirical pion vector form factor multiplied by a first-order polynomial in the squared invariant mass of the $\pi^{+} \pi^{-}$ system.

Abstract: Exclusive measurements of the reaction pp→dπ+π0pp→dπ+π0 have been carried out at Tp=1.1 GeVTp=1.1 GeV at the CELSIUS storage ring using the WASA detector. The isovector π+π0π+π0 channel exhibits no enhancement at low invariant ππ masses, i.e. no ABC effect. Therefore this most basic isovector double-pionic fusion reaction qualifies as an ideal test case for the conventional t-channel ΔΔ excitation process. Indeed, the obtained differential distributions reveal the conventional t-channel ΔΔ mechanism as the appropriate reaction process, which also accounts for the observed energy dependence of the total cross section.

Abstract: The production of omega mesons in the pd -> He-3 omega reaction has been studied at two energies near the kinematic threshold, T-p = 1450 MeV and T-p = 1360 MeV. The differential cross section was measured as a function of the omega c.m. angle at both energies over the whole angular range. Whereas the results at 1360 MeV are consistent with isotropy, strong rises are observed near both the forward and backward directions at 1450 MeV. Calculations made using a two-step model with an intermediate pion fail to reproduce the shapes of the measured angular distributions and also underestimate the total cross sections.

Abstract: Exclusive measurements of the pp-->pppi(+)pi(-) reaction have been carried out at T-p=775 MeV at CELSIUS using the PROMICE/WASA setup. Together with data obtained at lower energy, they point to a dominance of the Roper excitation in this process. From the observed interference of its decay routes N-*-->Nsigma and N-*-->Deltapi-->Nsigma, their energy-dependent relative branching ratio is determined.

Abstract: The DAΦNE Φ-factory is an ideal place to search for forces beyond the Standard Model. By using the KLOE detector, limits on U-boson coupling e 2 of the order of 10−5 ÷ 10−7 and on the αD × e 2 product have been set through the study of the Φ Dalitz decay, Uγ events and the Higgsstrahlung process. An improvement of these limits is expected thanks to the KLOE detector and DAΦNE upgrades of KLOE-2.

Abstract: The ratio Rη=Γ(η→π+π-γ)/Γ(η→π+π-π0) has been measured by analysing 22 million φ→ηγ decays collected by the KLOE experiment at DAΦNE, corresponding to an integrated luminosity of 558 pb-1. The η→π+π-γ proceeds both via the ρ resonant contribution, and possibly a non-resonant direct term, connected to the box anomaly. Our result, Rη=0.1856±0.0005stat±0.0028syst, points out a sizable contribution of the direct term to the total width. The di-pion invariant mass for the η→π+π-γ decay could be described in a model-independent approach in terms of a single free parameter, α. The determined value of the parameter α is α=(1.32±0.08stat-0.09syst+0.10±0.02theo) GeV-2.
