PRECISE DETERMINATION OF THE Kl - K ~ MASS DIFFERENCE BY THE GAP METHOD
نویسنده
چکیده
The Xl;, Es mass difference, Dm —= (Mz-Ms)c /h, has been redetermined in a highstatistics experiment performed at the zero-gradient synchrotron of Argonne National Laboratory, using the "gap method" originally developed at Princeton. Two independent measurements, using B4C and Cu, respectively, as regenerators, were performed and gave consistent results. Their mean is Am = (0.542+0.006) x 10 0 sec . With this value, the result of our recent determination of arg p + by "vacuum regeneratiod' is recalculated to be (44.7 + 5.0)', where the error allows for the uncertainty in Am given above.

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...
متن کاملK → ππ, KL-KS mass difference and the Dalitz decays of KL ∗
K → ππ, KL-KS mass difference, KL → γγ and the Dalitz decays of KL are studied systematically by assuming that their amplitude can be described in terms of a sum of short distance and long distance contributions. Dominance of the short distance effect on the KL-KS mass difference will be checked by the Dalitz decays of KL in a way consistent with the K → ππ and KL → γγ decays.

The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...
