Abstract
We measured K-series kaonic hydrogen X-rays in the SIDDHARTA experiment performed at the DAΦNE electron-positron collider of Laboratori Nazionali di Frascati. With a gaseous hydrogen target of density 15 ρSTP, preliminary values of the absolute yields, defined as the number of atomic X-rays emitted per kaon stopped inside the target, were determined to be 0.012−0.004+0.003 for Kα transition and 0.045−0.012+0.009 for Ktot, the summation of all the emitted K-series transitions.
