Kloe Perspectives for R-measurements at Dafne2
نویسنده
چکیده
As a future upgrade of the Frascati φ factory DAΦNE an increase of the center-of-mass energy of the accelerator up to W = 2 GeV has been proposed (DAFNE2). In this case the hadronic cross section in the energy range between 1−2 GeV can be measured with the KLOE detector. The feasibility of these measurements and the impact on the hadronic contribution to the anomalous magnetic moment of the muon, a μ , are discussed. The possibilities for an energy scan are compared with the radiative return technique, in which the accelerator is running at a fixed center-of-mass energy and ISR-events are taken to lower the invariant mass of the hadronic system.

Physics topics at KLOE - 2
The goal of the KLOE–2 experiment operating at the upgraded DA NE e+e− collider is to collect an integrated luminosity of about 20 fb−1 over 3-4 years of running. The KLOE–2 apparatus is now equipped with an inner tracker, new scintillation calorimeters and tagging detectors for γ γ physics. These will allow measurements to refine and extend the KLOE programme on kaon physics and tests of funda...

A preliminary measurement of R = Γ(K± → e±ν̄e)/Γ(K± → μ±ν̄μ) at the KLOE experiment is discussed. The result, R = (2.55± 0.05± 0.05)× 10−5, is based on 1.7 fb−1 of luminosity integrated on the φ -meson peak at the Frascati e+e− collider DAΦNE, corresponding to ∼8000 observed K± → e±ν̄e events. Perspectives on the methods planned to improve both the statistical and the systematic errors are briefly...
متن کاملSearching for KL → π0νν̄ at a Φ–factory
The perspectives of a search for the rare decay KL → πνν̄ at a Φ–factory are discussed. After a general analysis, we focus on the realistic case of KLOE and DAΦNE, showing that limits of the order of 10−9 on BR(KL → πνν̄) are achievable in the next few years. We also discuss the theoretical implications of this kind of measurements.

متن کاملMeasurement of the absolute branching ratio of the K + → π + π − π + ( γ ) decay with the KLOE detector
The absolute branching ratio of theK → πππ(γ) decay, inclusive of final-state radiation, has been measured using ∼17 million tagged K mesons collected with the KLOE detector at DAΦNE, the Frascati φ-factory. The result is: BR(K → πππ(γ)) = 0.05565 ± 0.00031stat ± 0.00025syst a factor ≃ 5 more precise with respect to the previous result. This work completes the program of precision measurements ...
