- W1600743501 abstract "We carry out a comparative analysis of three tests for the purpose of observing ${stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$ in a beam-dump experiment. The main source of ${stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$'s is determined to be the hadronic production of $F$ mesons, followed by the decay ${F}^{ifmmodepmelsetextpmfi{}}ensuremath{rightarrow}{ensuremath{tau}}^{ifmmodepmelsetextpmfi{}}{stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$. Possible signatures for various ${stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$-induced processes, together with their corresponding backgrounds, are examined. The muon-trigger test proposed earlier is found to be by far the most promising method. This test identifies ${stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$ events by the muonic decay mode of the ${ensuremath{tau}}^{ifmmodepmelsetextpmfi{}}$ produced in ${stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$ charged-current interactions, together with the requirements of substantial missing transverse momentum and distinctive behavior of certain azimuthal-angle distributions describing the emission of the muon, hadron shower, and direction of missing transverse momentum. It can be applied on an event-by-event basis, can separate ${ensuremath{nu}}_{ensuremath{tau}}$- and ${overline{ensuremath{nu}}}_{ensuremath{tau}}$-induced reactions, and is specific to ${stackrel{(ifmmodebarelsetextasciimacronfi{})}{ensuremath{nu}}}_{ensuremath{tau}}$. One should be able to use the test to determine directly whether ${ensuremath{nu}}_{ensuremath{tau}}$ is, indeed, a new, sequential neutrino. The test relies on the ability of recently developed neutrino detectors to measure the direction of the hadron shower. In addition to this muon-trigger test, we study the possibility of using two others, one based on the identification of events with two hadron showers, due to the semileptonic decay of the produced $ensuremath{tau}$, and the other based on the apparent neutral-to-charged-current event ratio. We find that neither of these two other tests seems feasible. However, it is expected that the muon-trigger test can be used in the near future to observe, for the first time, ${ensuremath{nu}}_{ensuremath{tau}}$ and ${overline{ensuremath{nu}}}_{ensuremath{tau}}$." @default.
