Pion decay widths of D mesons
✍ K.O.E. Henriksson; T.A. Lähde; C.J. Nyfält; D.O. Riska 📂 Article 📅 2001 🏛 Elsevier Science 🌐 English ⚖ 209 KB

The pionic decay rates of the excited L = 0, 1 D mesons are calculated with a Hamiltonian model within the framework of the covariant Blankenbecler-Sugar equation. The interaction between the light quark and charm antiquark is described by a linear scalar confining and a screened one-gluon exchange

We review several aspects of the phenomenology of P-wave ~Q mesons: mass splittings, effective strong couplings and leptonic constants. We also describe a QCD sum rule determination to order c~s of the form factor T1/2(y) governing the semileptonic B decays to the charm doublet with jR = (0 + 1 + ',

Results are reported on the precise measurement of the lifetime and the weak-decay branching ratios with charged particle(g-and proton) emission from k2C formed via 12C(~r+,K+) reaction. The It-mesonic decay width is consistent with the calculations including the pion wave function distortion effect

The M1 decay widths of charm and bottom mesons and their excited states are sensitive to the relativistic aspect of the quark current operators and obtain a significant contribution from the interaction current that is associated with the scalar confining interaction between heavy quarks (Q) and lig
