Ju n 20 09 Canonical interpretation of the η 2 ( 1870 )
نویسندگان
چکیده
We argue that the mass, production, total decay width, and decay pattern of the η 2 (1870) do not appear to contradict with the picture of it being the conventional 2 1 D 2 q ¯ q state. The possibility of the η 2 (1870) being a mixture of the conventional q ¯ q and the hybrid is also discussed.

The Tangent Cones at Double points of Prym-Canonical Divisors of Curves of genus 7
Let η be a line bundle on a smooth curve X with η^2=0 such that π_η, the double covering induced by η is an etale morphism. Assume also that X_η be the Prym-canonical model of X associated to K_X.η and Q is a rank 4 quadric containing X_η. After stablishing the projective normality of the prym-canonical models of curves X with Clifford index 2, we obtain in this paper a sufficient condition for...
متن کاملJu n 20 09 Orthogonal series and limit theorems for canonical U - and V - statistics of stationary connected observations
The limit behavior is studied for the distributions of normalized U-and V-statistics of an arbitrary order with canonical (degenerate) kernels, based on samples of increasing sizes from a stationary sequence of observations satisfying ϕ-or α-mixing. The corresponding limit distributions are represented as infinite multilinear forms of a centered Gaussian sequence with a known covariance matrix.

We analyze flavor-changing-neutral-current (FCNC) effects in the b→ s transitions that are induced by family non-universal U(1)′ gauge symmetries. After systematically developing the necessary formalism, we present a correlated analysis for the ∆B = 1, 2 processes. We adopt a model-independent approach in which we only require family-universal charges for the first and second generations and sm...
متن کامل00 4 Four sorts of meson
abstract An extensive spectrum of light non-strange q ¯ q states up to a mass of 2400 MeV has emerged from Crystal Barrel and PS172 data on ¯ pp → Resonance → A + B in 17 final states. These data are reviewed with detailed comments on the status of each resonance. For I = 0, C = +1, the spectrum is complete and very secure. Six 'extra' states are identified. Four of them have I = 0, C = +1 and ...
