M2 Signatures in Ψ(2s) Radiative Decays
Radiative decays of charmonium (cc̄) states are expected to be dominated by electric dipole (E1) transitions, with higher multipoles suppressed by powers of photon energy divided by quark mass [1]. (An early discussion of charmonium radiative transitions may be found in Ref. [2].) The search for contributions of higher multipoles is of interest as a source of information on the charmed quark’s m...
متن کاملSignatures of Supersymmetry and Yukawa Unification in Higgs Decays
We show that the branching ratio Rb/τ ≡ BR(h → b̄b)/BR(h → ττ) of the Higgs boson h may usefully differentiate between the Higgs sectors of the Minimal Supersymmetric Standard Model (MSSM) and non–supersymmetric models such as the Standard Model or its two Higgs doublet extensions. Although at tree level Rb/τ is the same in all these models, only in the MSSM can it receive a large radiative corr...
متن کاملOdd Decays from Even Anomalies: Gauge Mediation Signatures Without SUSY
We analyze the theory and phenomenology of anomalous global chiral symmetries in the presence of an extra dimension. We propose a simple extension of the Standard Model in 5D whose signatures closely resemble those of supersymmetry with gauge mediation, and we suggest a novel scalar dark matter candidate. ar X iv :0 90 1. 29 33 v1 [ he pph ] 1 9 Ja n 20 09
متن کاملThe Signatures Of Glueballs In J/ψ Radiative Decays
In this talk, I shall discuss the signatures of glueballs in the J/ψ radiative decays. Further experimental and theoretical investigations are suggested. The existence of glueballs and hybrids in nature has been one of the important predictions of the quantum chromodynamics(QCD). Considerable progress has been made recently in identifying the glueball candidates. In the scalar meson sector, the...
متن کاملSignatures of Supersymmetry in B Decays - A Theoretical Perspective
We discuss precision tests of the standard model in radiative and semileptonic rare B-decays and CP-violating asymmetries, and possible signatures of supersymmetry in these processes. Motivated by current data, and with an eye on the forthcoming measurements, we restrict ourselves to the processes in which the bench marks set by the standard model have either been met by ongoing experiments or ...
