We have searched for a light vector boson U, the possible carrier of "dark force", with KLOE detector at DAΦNE e+e− collider, motivated by astrophysical evidence presence dark matter in Universe. Using collisions collected an integrated luminosity 239.3 pb−1, we look dimuon mass peak reaction e+e−→μ+μ−γ, corresponding to decay U→μ+μ−. find no U signal. set 90% CL upper limit mixing parameter squared between photon and 1.6×10−5 8.6×10−7 region 520<mU<980 MeV.

Neutral kaon pairs produced in phi decays anti-symmetric entangled state can be exploited to search for violation of CPT symmetry and Lorentz invariance. We present an analysis the CP-violating process phi->K_S K_L->pi+pi-pi+pi- based on 1.7 fb-1 data collected by KLOE experiment at Frascati phi-factory DAFNE. The are used perform a measurement CPT-violating parameters Delta_amu neutral kaons contest Standard Model Extension framework. measured reference frame fixed stars are: Delta_ao =...

The long term goal of the CERN Experimental Physics Department R&D on monolithic sensors is development sub-100nm CMOS for high energy physics. first technology selected TPSCo 65nm imaging technology. A submission MLR1 included several small test chips with sensor and circuit prototypes transistor structures. One main questions to be addressed was how optimize in presence significant in-pixel circuitry. In this paper optimization described as well experimental results from run confirming its...

Part of the upgrade KLOE detector at DAΦNE Φ-factory consists insertion a tracking device around interaction region, composed four layers with radii from 130 mm to 205 and an active length 700 mm. Each layer was realized as cylindrical triple-GEM (CGEM) kapton-based detector, solution that allows us keep total material budget below 2% X0, utmost importance limit multiple scattering low-momentum tracks KLOE-2, minimize dead spaces. The peculiar readout pattern XV strips provides spatial...

We have studied the vector to pseudoscalar conversion decay ϕ→ηe+e−, with η→π0π0π0, KLOE detector at DAΦNE.
