Implication of the HyperCP boson X 0 ( 214 MeV ) in the flavour changing neutral current processes
نویسنده
چکیده
We analyze the inclusive b(c) → s(u)μ+μ− and the exclusive B(D+) → K(π+)μ+μ− flavour changing neutral current decays in the light of HyperCP boson X0 of mass 214 MeV recently observed in the hyperon decay Σ+ → p μ+μ−. Using the branching ratio data of the above inclusive and exclusive decays, we obtain constraints on g1 (h1) and g2 (h2), the scalar and pseudo-scalar coupling constants of the b− s−X0 (c− u−X0) vertices.

Search for a New Neutral Boson in the Rare Decay KL → π0π0μ+μ− from KTeV
The KTeV E799 experiment has conducted a search for the rare decay KL → π0π0μ+μ−, which includes a search for the light neutral boson X0 that decays to μ+μ−. A possible new light neutral boson X0 was reported by the HyperCP experiment with a mass of 214.3 MeV/c2. In this paper we report no evidence of KL → π0π0X0 → π0π0μ+μ− and set an upper limit on the branching ratio for KL → π0π0X0 → π0π0μ+μ...
متن کاملSearches for Flavour Changing Neutral Currents and Lepton Flavour Violation at HERA
A summary of the recent searches for anomalous single top-quark production and lepton flavour violation in high energy e±p collisions is presented. Single top-quark production via an anomalous flavour changing neutral current γ−u− t coupling would lead to the reaction ep → etX , t → Wb. H1 observed an excess of events above the Standard Model prediction in the leptonic decay channel of the W bo...

An upper limit on the branching ratio for the decay K + ! + is set at 2:4 10 9 at the 90% C.L. using pions in the kinematic region 214 MeV=c < P < 231 MeV=c. An upper limit of 5:2 10 10 is found on the branching ratio for decays K + ! + X 0 , where X 0 is any massless, weakly interacting neutral particle. Limits are also set for cases where M X 0 > 0. 1 The process K + ! + is highly suppressed ...

We study the neutral current flavour changing rare decay mode B → Kγγ within the framework of Standard Model, including the long distance contributions. It is found that these long distance contributions can be of the same order as the short distance contribution.
متن کاملEffects of the scalar FCNC in b → sl + l − transitions and supersymmetry
Effects of the scalar FCNC in b → sl + l − transitions and supersymmetry Abstract We investigate the potential effects of the scalar flavour changing neutral currents that are generated e.g. in supersymmetry with tan β ≫ 1 in the b → sl + l − transitions. Using the experimental upper limit on BR(B 0 s → µ + µ −) we place stringent model independent constraints on the impact these currents may h...
