Disentangling the K-complex of kaonic hydrogen with DEAR

The DEAR (DA Phi NE Exotic Atom Research) experiment at the new phi-factory DA Phi NE of Laboratori Nazionali di Frascati aims for a 1\% measurement of the line shift of the K-complex due to strong interaction in kaonic hydrogen. This presentation is meant to prove that the high statistics and good resolution obtainable with DEAR will be able to disentangle the kaonic hydrogen K-complex lines (a cascade unconstrained fit), obtaining in this way constraints for what concerns the cascade parameters and, consequently, information regarding the physical processes involved in the kaonic hydrogen atomic cascade.
