Abstract
KLOE has measured most decay branching ratios of K-S, K-L andK-+/--mesons. It has also measured the K-L and the K-+/- lifetime anddetermined the shape of the form factors involved in kaon semileptonicdecays. We present in the following a description of the abovemeasurements and a well organized compendium of all of our data, withparticular attention to correlations. These data provide the basis forthe determination of the CKM parameter vertical bar V-us vertical barand a test of the unitarity of the quark flavor mixing matrix. We alsotest lepton universality and place bounds on new physics usingmeasurements of vertical bar V-us vertical bar from K-l2 and K-l3decays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
