The CLEO experiment at the CESR collider has used 13.7 fb-1 of data to search for the production of the [Formula: see text] (css-ground state) in e+e- collisions at [Formula: see text]. The modes used to study the [Formula: see text] are Ω-π+, Ω-π+π0, Ξ-K-π+π+, Ξ0 K-π+, and Ω-π+π+π-. We observe a signal of 40.4±9.0(stat) events at a mass of 2694.6±2.6( stat })±1.9( syst ) MeV /c2, for all modes combined.

Using Data

Using data recorded by the CLEO II and CLEO II.V detectors at CESR, we report new measurements of the [Formula: see text] and [Formula: see text] masses, and the first measurements of their intrinsic widths. The measured widths of these particles agree with the theoretical predictions. We also present a new measurement of the mass of the [Formula: see text] charmed baryon, observed by its decay into [Formula: see text], and the first observation of a new state which is identified as the [Formula: see text], the isospin partner of the previously discovered [Formula: see text] and [Formula: see text]. The quark model predicts many excited states of Λc and Σc baryons, some of which cannot, because of quantum mechanical conservations rules, decay via one pion to the ground state. We present results of a search for such states decaying via dipion decays into the ground state [Formula: see text] Recently, The CLEO collaboration also reported the existence of a pair of excited Ξc particles decaying into [Formula: see text]. These are thought to be orbitally excited Ξc' s with JP = 3/2-. Here we present a search for the analogous JP=1/2- particles, which are predicted to decay into [Formula: see text].

The phenomenon of bioluminescence has fascinated layman and scientist alike for many centuries. During the eighteenth and nineteenth centuries a number of observations were reported on the physiology of bioluminescence in Renilla, the common sea pansy. More recently biochemists have directed their attention to the molecular basis of luminosity in this colonial form. These studies have centered primarily on defining the chemical basis for bioluminescence and its control. It is now established that bioluminescence in Renilla arises due to the luciferase-catalyzed oxidation of luciferin. This results in the creation of a product (oxyluciferin) in an electronic excited state. The transition of oxyluciferin from its excited state to the ground state leads to light emission.
