The Long Distance Contribution to D → πl + l −
نویسندگان
چکیده
We calculate the long distance contribution to D +,0 → π +,0 l + l − decays by the use of a vector meson dominance model, in which the φ-meson plays the central role. The branching ratios obtained are 10 −6 and a few times 10 −7 for the resonance and non-resonance regions respectively. The analysis includes a calculation of D + → π + φ, consistent with the experimental value.

PROBING c → uγ IN Bc → B ∗ uγ DECAY a
Flavour changing neutral current (FCNC) transitions c → uγ and c → ul + l − are very rare in the standard model and present an interesting probe for the physics beyond it. We study long distance contamination to these short distance processes in different hadron decays. As the most suitable probe for c → uγ transition we propose Bc → B * u γ decay. Its detection at the branching ratio well abov...

Let X be a compact, connected, Riemannian manifold (without boundary), ρ be the geodesic distance on X, μ be a probability measure on X, and {φk} be an orthonormal (with respect to μ) system of continuous functions, φ0(x) = 1 for all x ∈ X, {`k} ∞ k=0 be an nondecreasing sequence of real numbers with `0 = 1, `k ↑ ∞ as k → ∞, ΠL := span {φj : `j ≤ L}, L ≥ 0. We describe conditions to ensure an e...

We explore the sensitivity of the flavour changing neutral currents among c and u quarks in the context of the Minimal Supersymmetric Standard Model. The standard model rate for c → uγ can be enhanced by up to two orders of magnitudes in general MSSM, while the c → ul + l − rate can be enhanced by at most a factor of three. The most suitable hadronic observable to probe the c → uγ transition is...
متن کاملRare Charm Decays in the Standard Model and Beyond
We perform a comprehensive study of a number of rare charm decays, incorporating the first evaluation of the QCD corrections to the short distance contributions, as well as examining the long range effects. For processes mediated by the c → ul+l− transitions, we show that sensitivity to short distance physics exists in kinematic regions away from the vector meson resonances that dominate the to...

Let K be a complete local field of characteristic p with perfect residue field. Let L/K be a finite, fully ramified, Galois p-extension. If πL ∈ L is a prime element, and p(x) is the derivative of πL’s minimal polynomial over K, then the relative different DL/K is generated by p ′(πL) ∈ L. Let vL be the normalized valuation normalized with vL(L) = Z. We show that any element ρ ∈ L with vL(ρ) ≡ ...
