Storage ring proton EDM experiment

<!--HTML--><p>I will give a overview of the present status of the electric dipole moment (EDM) experiments and then I will focus on the proton EDM method to be performed in an all-electric storage ring.&nbsp; In storage rings one has the chance to probe the EDM of the proton with unprecedented<br /> sensitivity of 10^-29 e-cm.&nbsp;</p> <p>The strength of the method originates from the fact that there are high intensity polarized proton beams available and the fact that the so-called geometric phase systematic error background cancels with clock-wise and counter-clock-wise storage possible in electric rings. The ultimate sensitivity of the method is 10^-30 e-cm. At this level it will either detect a non-zero EDM or it will eliminate electro-weak baryogenesis.</p>
