Study of χ c 1 and χ c 2 meson production in B meson decays
Using a sample of 9.7 × 10 BB meson pairs collected with the CLEO detector, we study B decays to the χc1 and χc2 charmonia states, which are reconstructed via their radiative decays to J/ψ. We first measure the branching fraction for inclusive χc1 production in B decays to be B(B → χc1X) = (4.14 ± 0.31 ± 0.40) × 10 , where the first uncertainty is statistical and the second one is systematic. W...
متن کاملImplementing χ
Calculi are used to reason about functional languages from a theoretical perspective. They allows us to make bold statements about programs based on sound and correct deductive methods. Methods of visualization allow us to gain a better understanding of the communication and interaction involved between processes. Often, graphs are used because of the level of intuition they can bring to a syst...
متن کاملAmalgams and χ-Boundedness
A class of graphs is hereditary if it is closed under isomorphism and induced subgraphs. A class G of graphs is χ-bounded if there exists a function f : N → N such that for all graphs G ∈ G, and all induced subgraphs H of G, we have that χ(H) ≤ f(ω(H)). We prove that proper homogeneous sets, clique-cutsets, and amalgams together preserve χ-boundedness. More precisely, we show that if G and G∗ a...

متن کاملOn the period history of χ Cygni
We discuss the light variability of the Mira variable χ Cygni, present a homogeneous set of times of minimum and maximum light since its discovery date in 1686, and analyse the variations of the pulsation period. There is a substantial cycleto-cycle variation in the pulsations (standard error ∼ 6. d5) with quite strong evidence for a linearly increasing period. Quasicyclic patterns in the O−C d...
