WebFeb 1, 2024 · We propose to measure the decay in order to determine the axial vector mixing angle . We derive, for the first time, the differential decay rate formula for this decay mode. Using the obtained result, we perform a sensitivity study for the Belle (II) experiment.

Web3. The ρ has the quantum numbers of π π coupled to I = 1. If they only list particles stable under the strong interaction then τ − → ρ − ν is the same as τ − → π − π 0 ν, which indeed has a branching ratio of 25%. The table is more helpful than that: It lists the non-resonant (non ρ) part of τ → π − π 0 ν, which ... WebDec 26, 2012 · TauDecay is a library of helicity amplitudes to simulate polarized tau decays, constructed in the FeynRules and MadGraph5 framework. Together with the leptonic mode, the decay library includes the ...
WebThe existence of the tau neutrino has relied on the indirect (though very strong) evidence until this past summer. The initial evidence was presented by Feldman et al [6] in 1981 from tau decay data. The DONUT experiment [7] at Fermilab has now reported the first direct observations of detected ντinteractions. WebSep 12, 2024 · Save as PDF Page ID ... Therefore, muon-lepton number is conserved. Neither electrons nor tau are involved in this decay, so \(L_e = 0\) and \(L_{\tau} = 0\) for …
WebA decay momentum p is given for each decay mode. For a 2-body decay, p is the momentum of each decay product in the rest frame of the decaying particle. For a 3-or-more-body decay, p is the largest momentum any of the products can have in this frame Reply [deleted]• Additional comment actions [removed] Reply More posts you may like
