The branching ratio for the decay K + → π + ν ¯ ν is sensitive to new physics; the NA62 experiment will measure it to within about 10%. To reject the dominant background from channels with final state photons, the large-angle vetoes (LAVs) must detect particles with better than 1 ns time resolution and 10% energy resolution over a very large energy range.(More)
In the fixed energy environment of the e + e − collider DAΦNE, KLOE can measure the cross section of the process e + e − → hadrons as a function of the hadronic system energy using the radiative return method. At energies below 1 GeV, e + e − → ρ → π + π − is the dominating hadronic process. We report here on the status of the analysis of the process e + e(More)
The importance of self-assembling peptides (SAPs) in regenerative medicine is becoming increasingly recognized. The propensity of SAPs to form nanostructured fibers is governed by multiple forces including hydrogen bonds, hydrophobic interactions and π-π aromatic interactions among side chains of the amino acids. Single residue modifications in SAP(More)
—The branching ratio (BR) for the decay K + → π + ν ¯ ν is a sensitive probe for new physics. The NA62 experiment at the CERN SPS will measure this BR to within about 10%. To reject the dominant background from channels with final state photons, the large-angle vetoes (LAVs) must detect photons of energy as low as 200 MeV with an inefficiency of less than(More)
± ν) between the two leptonic decay rates of charged kaons is precisely predicted within the Standard Model (SM). A recent theoretical work noticed that SUSY extensions of the SM can induce mu-electron universality violation in such a way to introduce a shift of the R K value up to few percent respect to SM prediction. Presently the experimental relative(More)
The KLOE detector at DAΦNE , the Frascati φ-factory, has collected about 30 pb −1 by the end of year 2000. The φ(1020) meson decays about 34% of the times into a K 0 L-K 0 S pair; DAΦNE is therefore an exceptional source of almost monochromatic, tagged K 0 S particles, allowing for detailed studies of their more rare decays. The above mentioned integrated(More)
We present a study of the reaction e + e − →π + π − γ at the φ peak with the KLOE detector at the φ–factory DAΦNE. This reaction allows us to obtain the cross section for e + e − →π + π − from the e + e − center-of-mass energy W = m φ = 1019 MeV down to threshold, i.e. 2m π < M ππ < m φ. This is called radiative return. The status of the analysis and(More)
