Radiative decays of heavy and light mesons in a quark triangle approach.
نویسندگان
چکیده
The radiative meson decays V → Pγ and P → γγ are analyzed using the quark triangle diagram. Experimental data yield well determined estimates of the universal quark-antiquark-meson couplings gV qq̄′ and gPqq̄′ for the light meson sector. Also predictions for the ratios of neutral to charged heavy meson decay coupling constants are given and await experimental confirmation. 13.25.-k, 12.40.Vv, 13.40.Hq, 14.40.-n Typeset using REVTEX 1

Vector 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 کاملCharm 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...

The radiative decays of heavy baryons and lowest three doublets of heavy mesons are studied with the light cone QCD sum rules in the leading order of heavy quark effective theory. PACS number: 12.39.Hg, 13.40.Hq, 12.38.Lg
متن کاملCorrections to chiral dynamics of heavy hadrons: SU(3) symmetry breaking.
In previous publications we have analyzed the strong and electromagnetic decays of heavy mesons and heavy baryons in a formalism which incorporates heavy-quark and chiral symmetries. There are two possible symmetry-breaking e ects on the chiral dynamics of heavy hadrons: the nite-mass e ects from light quarks and the 1=mQ corrections from heavy quarks. In the present paper, chiral-symmetry-brea...
متن کاملRadiative heavy meson transitions
We evaluate the radiative and hadronic decay rates of the D mesons using the Heavy Quark Effective Theory and the Vector Meson Dominance hypothesis. We also estimate the width of the B electromagnetic transitions and the radiative decays of positive parity J = 0, 1 charmed mesons. e-mail address: [email protected] In this letter we wish to show that the heavy quark and chiral SU(3)L × SU(3...
