Nonresonant Three-body Decays of D and B Mesons

Nonresonant three-body decays of D and B mesons are studied. It is pointed out that if heavy meson chiral perturbation theory (HMChPT) is applied to the heavy-light strong and weak vertices and assumed to be valid over the whole kinematic region, then the predicted decay rates for nonresonant charmless 3-body B decays will be too large and especially B− → π−K+K− greatly exceeds the current expe...

Charmless 3-body B Decays: Resonant and Nonresonant Contributions

Charmless 3-body decays of B mesons are studied using a simple model based on the framework of the factorization approach. We have identified a large source of the nonresonant signal in the matrix elements of scalar densities, e.g. 〈KK|s̄s|0〉. This explains the dominance of the nonresonant background in B → KKK decays, the sizable nonresonant fraction of order (35 ∼ 40)% in Kππ and K 0 ππ modes ...

Three - Body Decays of the Proton

The rates for the three-body proton decays p + Irlre+ are related o+ to the rate for the decay p + TI e . This is done by making an ansatz for the form of the three-body amplitude which is consistent with current algebra and with the measured TIT final state interactions. We find that the three-body decay rates are comparable with the rate for the two-body decay p -+ roe+. Submitted to Physical...

Testing Gluino Spin with Three-Body Decays

We examine the possibility of distinguishing a supersymmetric gluino from a KaluzaKlein gluon of universal extra dimensions (UED) at the Large Hadron Collider (LHC). We focus on the case when all kinematically allowed tree-level decays of this particle are 3-body decays into two jets and a massive daughter (typically weak gaugino or Kaluza-Klein weak gauge boson). We show that the shapes of the...

Three–Body Decays of SUSY Particles

We analyze the decays of charginos, neutralinos, gluinos and the first/second generation squarks in the Minimal Supersymmetric extension of the Standard Model, focusing on the three–body decays in scenarios where the ratio tan β of vacuum expectation values of the two Higgs doublet fields is large. We show that the three– body decays of the next–to–lightest neutralinos (lightest charginos) into...
