“…The ωγπ transition form factor can be reproduced taking the contribution of the groundstate ρ-meson and at least one excited ρ-meson into account. The extended VMD model with m ρ = 769 MeV and m ρ ′ = 1450 MeV provides the correct asymptotics and yields a better description of the experimental data [47,48] than the one-pole model with only the ground-state ρ-meson. However, it still underestimates the slope of the form factor at t = 0.…”

The invariant mass spectrum of the e + e − and µ + µ − pairs from decays of light unflavored mesons with masses below the φ(1020)-meson mass to final states containing along with a dilepton pair one photon, one meson, and two mesons are calculated within the framework of the effective meson theory.The results can be used for simulations of the dilepton spectra in heavy-ion collisions and for experimental searches of dilepton meson decays.

“…In addition, this is the most common decay mode in studies where a Λ þ c baryon is included in the final state of the decay chain, such as the exclusive and inclusive decay rate measurements of bflavored mesons and baryons or the measurements of fragmentation fractions of charm and bottom quarks. The Particle Data Group combines several measurements from the ARGUS and CLEO Collaborations [2][3][4][5][6][7][8] to determine BðΛ þ c → pK − π þ Þ ¼ ð5.0 AE 1.3Þ%, where the dominant contribution to the quoted uncertainty originates from the model dependence of the branching fraction extraction [9]. A precise measurement of the branching fraction BðΛ þ c → pK − π þ Þ can, therefore, significantly improve the precision of branching fractions of other Λ þ c decays and, also, those of decays of b-flavored mesons and baryons involving Λ þ c .…”

We present the first model-independent measurement of the absolute branching fraction of the Λ(c)(+) → pK(-)π(+) decay using a data sample of 978 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The number of Λ(c)(+) baryons is determined by reconstructing the recoiling D((*)-) pπ(+) system in events of the type e(+)e(-) → D((*)-) pπ(+)Λ(c)(+). The branching fraction is measured to be B(Λ(c)(+) → pK(-)π(+)) = (6.84 ± 0.24(-0.27)(+0.21))%, where the first and second uncertainties are statistical and systematic, respectively.

A direct evaluation of the Λc+ absolute branching ratios: a new approach

et al. 1999

View full text Add to dashboard Cite

A novel method for a direct measurement of the exclusive Λ + c branching ratios is here described. The approach is based on the peculiar topology of the quasi-elastic charm neutrino-induced events on nucleons. The intrinsic potentiality of the method is thoroughly discussed using a perfect detector. As an application, the statistical accuracy reachable with existing data sample has been estimated. From a theoretical point of view, such measurement provides a better understanding of the baryonic b-decays. Submitted to Physics Letters B1 Now also at the INFN, Sezione di Napoli, Italy
