Abstract:

We search and find no evidence for CP violation in tau decays into the K(pi)nu(tau) final state. We provide limits on the imaginary part of the coupling constant Lambda describing a relative contribution of the CP violating processes with respect to the standard model to be -0.172

Abstract:

This paper presents the design and first measurements on the version 1.2 of the Beetle chip.The Beetle is a 128 channel pipelined readout chip which is intended for the silicon vertex detector, the inner tracker and the pile-up veto trigger of LHCb. In case of multianode photomultiplier tubes being used for the RICH readout, it is foreseen also to use the Beetle.Section II. gives a short overview of the chip architecture whereas section III. shows first measurements on the Beetle 1.2. In section IV. the results from a Total Ionizing Dose (TID) irradiation test is summarized, while an outlook on further tests given in section V.
