Abstract: | The CAST Experiment completed its first phase in the end of 2004, after having run successfully for two years. The results of the data analysis of the Micromegas detector at CAST for 2003 and a first result of 2004 are presented here. This experiment has a sensitivity of almost a factor 100 better compared with previous searches. The coupling constant of axions of mass up to 0.02 eV to photons has been restricted with a 95% Confidence Level to gαγ≤ 1.50 x 10-10 GeV-1 for the 2003 Micromegas detector [and ga ≤ 1.16 × 1010 GeV1 after combining the result of all the detectors of the experiment]. The preliminary limit acquired for the 2004 data is more strict, at gαγ≤ 1.21 x 10-10 GeV-1 concerning the Micromegas detector. |
