چکیده
We have calculated the decay τ → νπ(K)γ. We present the photon energy spectrum, the meson-photon invariant mass spectrum and the integrated rate as a function of a photon energy cut or an invariant mass cut. Both the internal bremsstrahlung and the structure dependent radiation have been taken into account. To this aim we have parametrized the form factors FV and FA, which determine the structure dependent radiation. Observables especially suited for the measurement of the structure dependent form factors are found and implications on the width of the a1 discussed.

Charm meson radiative decays
Combining heavy quark effective theory and the chiral Lagrangian approach we investigate D meson radiative decays. First, we reanalyse D∗ → Dγ decays using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. Then, we calculate branching ratios D → V γ. We make some comments on the Cabbibo suppressed decays D → ρ/ωγ and the branching ratios of D → P...
متن کاملMeson loops in the f 0 ( 980 ) and a 0 ( 980 ) radiative decays into ρ , ω
Meson loops in the f 0 (980) and a 0 (980) radiative decays into ρ, ω Abstract. We calculate the radiative decay widths of the a0(980) and f0(980) scalar mesons into ργ and ωγ considering the dynamically generated nature of these scalar resonances within the realm of the Chiral Unitary Approach. The main ingredient in the evaluation of the radiative width of the scalar mesons are the loops comi...
متن کاملVector and pseudoscalar charm meson radiative decays.
Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar D mesons. We first reanalyse D∗ → Dγ decays within the effective Lagrangian approach using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. We then investigate D → V γ decays and calculate the D → K̄∗0γ and D → ργ partial widt...
متن کاملDecay of light scalar mesons into vector-photon and into pseudoscalar mesons
The decays of a light scalar meson into a vector meson and a photon (S → V γ) are evaluated in the tetraquark and quarkonium assignments of the scalar states. A link with the radiative decays φ → Sγ is established: experimental results for S → V γ will allow to understand if the direct, quark-loop contribution to φ→ Sγ or the kaon-loop contribution is dominant. Also strong decays S → PP -where ...
متن کاملHidden gauge formalism for the radiative decays of axial-vector mesons
The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS) formalism. The formalism is well suited to study this problem since it deals with pseudoscalar and vector mesons in a unified way, respecting chiral invariance. We show explicitly the gauge invariance of the set of d...
