Observation of decays to and $π^+π^-\e^+e^-$
CLEO Collaboration, P. Naik
Using psi(2S) --> pi+ pi- J/psi, J/psi --> gamma eta' events acquired with the CLEO-c detector at the CESR e+e- collider, we make the first observations of the decays eta' --> pi+…
Observation of J/psi --> 3 gamma
CLEO Collaboration, G. S. Adams
We report the first observation of the decay J/psi --> 3 gamma. The signal has a statistical significance of 6 sigma and corresponds to a branching fraction of B(J/psi --> 3 gamma)…
Measurement of the eta'-meson mass using J/psi--> gamma eta'
CLEO Collaboration, J. Libby
We measure the mass of the eta' meson using psi(2S)--> pi+ pi- J/psi, J/psi--> gamma eta' events acquired with the CLEO-c detector operating at the CESR e+e- collider. Using three…
J/psi and psi(2S) Radiative Transitions to eta_c
CLEO Collaboration, R. E. Mitchell
Using 24.5 million psi(2S) decays collected with the CLEO-c detector at CESR we present the most precise measurements of magnetic dipole transitions in the charmonium system. We me…
On "non-Hermitian Quantum Mechanics"
Mark J. Everitt, Shaaban Khalil, Alexandre M. Zagoskin
A series of recent papers ``Faster than Hermitian Quantum Mechanics'' and related articles made a point of the possibility of a non-Hermitian, but PT-symmetric, operator to play th…
Sterile neutrino dark matter in extension of the standard model and galactic 511 keV line
Shaaban Khalil, Osamu Seto
Sterile right-handed neutrinos can be naturally embedded in a low scale gauged extension of the standard model. We show that, within a low reheating scenario, such a n…
Signatures for right-handed neutrinos at the Large Hadron Collider
Katri Huitu, Shaaban Khalil, Hiroshi Okada +1
We explore possible signatures for right-handed neutrinos in TeV scale B-L extension of the Standard Model (SM) at the Large Hadron Collider (LHC). The studied four lepton signal h…
Absolute Measurement of Hadronic Branching Fractions of the D_s^+ Meson
CLEO Collaboration, J. Alexander
The branching fractions of D_s meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 /pb of e+ e- collisions recorded at a center of mass…
