Abstract

We investigate the discovery potential of cubic-kilometer neutrino observatories such as IceCube to set stringent limits on the forbidden decays {eta}{yields}{nu}{sub e{nu}e} and {eta}{yields}{nu}{sub {tau}{nu}{tau}.} The signatures for these decays are cascade events resulting from the charged-current reactions of {nu}{sub e}, {nu}{sub {tau},} {nu}{sub e}, and {nu}{sub {tau}}on nuclei in such detectors. Background cascade events are mainly due to {nu}{sub e}'s from atmospheric {mu}, K{sup +}, and K{sub S}{sup 0} decays and to a lesser extent from atmospheric {nu}{sub {mu}}neutral-current interactions with nuclei. A direct upper limit for the branching ratio {eta}{yields}{nu}{sub e,{tau}{nu}e,{tau}}of 6.1x10{sup -4} at 90% CL can be achieved.

Measurement of the {tau}{sup -}{yields}{eta}{pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} branching fraction and a search for a second-class current in the {tau}{sup -}{yields}{eta}{sup '}(958){pi}{sup -}{nu}{sub {tau}} decay

Journal Article Aubert, B; Bona, M; Boutigny, D; ... - Physical Review. D, Particles Fields

The {tau}{sup -}{yields}{eta}{pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} decay with the {eta}{yields}{gamma}{gamma} mode is studied using 384 fb{sup -1} of data collected by the BABAR detector. The branching fraction is measured to be (1.60{+-}0.05{+-}0.11)x10{sup -4}. It is found that {tau}{sup -}{yields}f{sub 1}(1285){pi}{sup -}{nu}{sub {tau}}{yields}{eta}{pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} is the dominant decay mode with a branching fraction of (1.11{+-}0.06{+-}0.05)x10{sup -4}. The first error on the branching fractions is statistical and the second systematic. Note that no particle identification algorithm is applied to the charged tracks to distinguish pions from kaons.

Study of the Tau- to Pi- Pi+ Pi- Pi0 Nu/Tau And Tau- to Pi- Pi- Pi+ Eta Nu/Tau Decays Using the BaBar Detector

Conference Sobie, Randall - Nucl.Phys.Proc.Suppl.169:44-49,2007

The {tau}{sup -} {yields} {pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} and {tau}{sup -} {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}{eta}{nu}{sub {tau}} decays have been studied with the BABAR detector. Preliminary branching fractions on the two modes are presented. The {tau}{sup -} {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}{eta}{nu}{sub {tau}} mode is found to have a large contribution from the {tau}{sup -} {yields} {omega}{pi}{sup -}{nu}{sub {tau}} decay. The {tau}{sup -} {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}{eta}{nu}{sub {tau}} decay is studied using the {eta} {yields} {gamma}{gamma} mode and the {tau}{sup -} f{sub 1}(1285){pi}{sup -}{nu}{sub {tau}} decay is seen to be the primary source of these decays.

We report on analyses of tau lepton decays {tau}{sup -}{yields}{eta}K{sup -}{nu}{sub {tau}} and {tau}{sup -}{yields}{eta}{pi}{sup -}{nu}{sub {tau}}, with {eta}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0}, using 470 fb{sup -1} of data from the BABAR experiment at PEP-II, collected at center-of-mass energies at and near the {Upsilon}(4S) resonance. We measure the branching fraction for the {tau}{sup -}{yields}{eta}K{sup -}{nu}{sub {tau}} decay mode, B({tau}{sup -}{yields}{eta}K{sup -}{nu}{sub {tau}})=(1.42{+-}0.11(stat){+-}0.07(syst))x10{sup -4}, and report a 95% confidence level upper limit for the second-class current process {tau}{sup -}{yields}{eta}{pi}{sup -}{nu}{sub {tau}}, B({tau}{sup -}{yields}{eta}{pi}{sup -}{nu}{sub {tau}})<9.9x10{sup -5}.

Journal Article Aubert, B; Karyotakis, Y; Lees, J; ... - Physical Review Letters

Using 467 fb{sup -1} of e{sup +}e{sup -} annihilation data collected with the BABAR detector, we measure (B({tau}{sup -{yields}}{mu}-{nu}{sub {mu}{nu}{tau}}))/B({tau}{sup -{yields}}e{sup -{nu}}{sub e{nu}{tau}})=(0.9796{+-}0.0016{+-}0.0036), (B({tau}{sup -{yields}}{pi}-{nu}{sub {tau}})/B({tau}{sup -{yields}}e{sup -{nu}}{sub e{nu}{tau}}))=(0.5945{+-}0.0014{+-}0.0061), and (B({tau}{sup -{yields}}K{sup -{nu}}{sub {tau}})/B({tau}{sup -{yields}}e{sup -{nu}}{sub e{nu}{tau}}))=(0.03882{+-}0.00032{+-}0.00057), where the uncertainties are statistical and systematic, respectively. From these precision {tau} measurements, we test the standard model assumption of {mu}-e and {tau}-{mu} charge current lepton universality and provide determinations of |V{sub us}| experimentally independent of the decay of a kaon.
