چکیده
We present new results on the related rare K L decay modes K 0 L ! + and K L ! + ee . KTeV has performed the rst direct measurement of the form factor for the \direct emission" component of K L ! + decays, a quantity with rami cations for particular chiral models. In addition, the form factor and direct emission/inner bremsstrahlung branching ratio | also presented here | are important input parameters for the understanding of the planar{ angle distribution of K L ! + ee decays. Preliminary results indicating the presence of a T{violating asymmetry in the K L ! + ee angular distribution are presented.

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کامل– 1 – Rare Kaon Decays
A. Introduction: There are several useful reviews on rare kaon decays and related topics [1–14]. Activity in rare kaon decays can be divided roughly into four categories: 1. Searches for explicit violations of the Standard Model 2. Measurements of Standard Model parameters 3. Searches for CP violation 4. Studies of strong interactions at low energy. The paradigm of Category 1 is the lepton flav...

We report the results of a blind search for flavor-changing neutral current (FCNC), lepton-flavor violating, and lepton-number violating decays of D, D s , and D 0 mesons (and their antiparticles) into 2–, 3–, and 4–body states including a lepton pair. Such decays may involve Flavor-Changing Neutral Currents, Leptoquarks, Horizontal Gauge Bosons, or Majorana Neutrinos. No evidence for any of th...

We report the results of a search for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D+, D+ s , and D 0 mesons (and their antiparticles) into modes containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, we examine the πll and Kll decay modes of D+ and D+ s and the l +l− decay modes of D0. No evidence for a...
متن کاملSU(3)- Flavor Symmetry in B → V P Decays
In the framework of SU (3) symmetry, we present a general analysis of B meson decays into two lighter uncharmed mesons (both pairs of pseudoscalar mesons and pairs of vector and pseudoscalar mesons). From the analysis we find constraints on γ and discuss their validity. The most useful new constraint is obtained by considering the decay modes B 0 → Kπ and B + → π 0 π +. In decays into pairs of ...
