MEASUREMENT OF THE KAON MASS DIFFERENCE mL-mS BY THE TWO REGENERATOR METHOD
نویسندگان
چکیده
Introduction. In this letter we report briefly the result of a measurement of the mass difference Am = mLms, where mL and ms are the masses of the long and short lived neutral kaons respectively. The experimental details will be presented more completely elsewhere. The method consists of the comparison of the intensity of the KS regenerated from a K, beam in two slabs of matter separated at different distances 111. The intensity of n+ndecay observed after the second regenerator is given approximately*’ by relation (1):

Effects of periodic matter in kaon regeneration
We study the effects of periodic matter in kaon regeneration, motivated by the possibility of parametric resonance in neutrino oscillations. The large imaginary parts of the forward kaon-nucleon scattering amplitudes and the decay width difference ∆Γ prevent a sizable enhancement of the KL → KS transition probability. However, some interesting effects can be produced using regenerators made of ...

Introduction. The experiment reported in this paper is part of an extensive study aiming principally at a more precise determination of #+_ , the phase of q+_ , the parameter describing CP-violation in K” + 7~+trdecays. New values of K” + n+ndecay parameters have been reported previously [ 1 ] . The data on semi-leptonic kaon decays recorded simultaneously and in the same apparatus as the pioni...

A rapid and sensitive liquid chromatography–tandem mass spectrometry (LC-MS) method was developed for the determination of enalapril and enalaprilat in human plasma. Detection of analytes was achieved by tandem mass spectrometry with electrospray ionization (ESI) interface in positive ion mode which was operated under the multiple-reaction monitoring mode. Sample pretreatment was involved...
