“…We follow here the standard quark model for simplicity as far as possible in the hope that some problems may disappear with improved calculations. The qq assumption is supported by various observations which are not natural for a complex 4q state: the close similarity in various production properties with other quarkonia of similar mass (like ρ, φ(1020), a 0 (980), η ′ , in both e + e − annihilation [11] and νp interactions [12], see recent review [13]); the dominance of f 0 (980) production at large momentum transfer |t| ∼ 0.5 GeV 2 in πp collisions [14] which suggests a f 0 πA 1 coupling [6]; the strong production in D, D s decays (see below) through intermediate dd and ss states. This discussion will have to continue until a consistent description of all phenomena is achieved.…”

“…Such an effect is actually visible in the Dalitz plot at the ρ resonance (presumably from the (ρ − f 0 (980) interference): the sign change of the asymmetry causes the appearence of the tails towards lower and higher mass (s 12 ) at the upper and lower part (s 13 ) of the ρ band respectively. A study with sufficiently fine binning should reveal this effect for the σ in the resonance Monte Carlo for the σ + ρ superposition and prove or disprove the presence of the interference effect in the data (a sensitive observable is cos ϑ dσ ds 12 together with dσ ds 12 ).…”

Abstract. We discuss the classification of the light scalar mesons with mass below 2 GeV into qq nonets and glueballs. The information on production and decay of these states, in particular recent information on the f 0 (980), f 0 (400 − 1200) (or σ(600)) and f 0 (1500) is considered. Although the data are not yet very precise the recent information is in favour of the previously developed scheme which includes f 0 (980), a 0 (980), K * 0 (1430), f 0 (1500) into the lightest scalar nonet. The glueball in this approach appears as broad object around 1 GeV. Alternative schemes find the glueball at somewhat higher mass or suggest his mixing with qq states spread over a similar mass range. We do not see sufficient evidence yet for a light scalar nonet below 1 GeV around a σ(600) resonance.

“…The NOMAD experiment conducted several other measurements: inclusive production of resonances [38], Bose-Einstein correlations in ] CC interactions [39], ] -nucleon cross-section off an isoscalar target [40], study of quasielastic events [41], coherent neutral pion production [42], single photon production [43], and backward going particles [44]. Also some more exotic ideas were tested: search for a new gauge boson [45], search for eV scalar penetrating particles [46], and search for heavy neutrinos [47].…”

The NOMAD Experiment at CERN

The purpose of this paper is to review the experimental apparatus and some physics results from the NOMAD (neutrino oscillation magnetic detector) experiment which took data in the CERN wide-band neutrino beam from 1995 to 1998. It collected and reconstructed more than one million charged current (CC)νμevents with an accuracy which was previously obtained only with bubble chambers. The main aim of the experiment was to search for the oscillationνμintoντ, in a region of mass compatible with the prescriptions of the hot dark matter hypothesis, which predicted aντmass in the range of 1–10 eV/c2. This was done by searching forντCC interactions, observing the production of theτlepton through its various decay modes by using kinematical criteria. In parallel, NOMAD also strongly contributed to the study of more conventional processes: quasielastic events, strangeness production and charm dimuon production, single photon production, and coherent neutral pion production. Exotic searches were also investigated. The paper reviews the neutrino beam, the detector setup, the detector performances, the neutrino oscillation results, the strangeness production, the dimuon charm production, and summarizes other pieces of research.
