Two-Pion Production in Nucleon-Nucleon Collisions and the ABC-Effect - Approaching a Puzzleby exclusive and Kinematically complete Measurements
T. Skorodko, M. Bashkanov, C. Bargholtz +50
The ABC effect - a puzzling low-mass enhancement in the invariant mass spectrum - is known from inclusive measurements of two-pion production in nuclear collisions, where it a…
Evidence for a 'Narrow' Roper Resonance - the Breathing Mode of the Nucleon
H. Clement, T. Skorodko, M. Bashkanov +43
All the time since its discovery the N(1440) baryon state, commonly known as Roper resonance, has been a state with many question marks - despite of its 4-star ranking in the p…
Observation of the decay Upsilon(4S) -> Upsilon(1S) pi+ pi-
The Belle Collaboration
We study transitions between Upsilon states with the emission of charged pions using 477 fb^{-1} of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- colli…
A Search for the Rare Leptonic Decays B+ -> mu+ nu and B+ -> e+ nu
N. Satoyama
We present a search for the decays B+ -> mu+ nu_mu and B+ -> e+ nu_e in a 253 fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energ…
Search for Invisible Decay of the
The Belle Collaboration, O. Tajima, H. Hayashii +4
We report results of a search for the invisible decay of the Upsilon(1S) via the Upsilon(3S)->pi+pi-Upsilon(1S) transition using a data sample of 2.9 fb^{-1} at the Upsilon(3S) res…
Measurement of the ratio Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0)
K. Abe
We report a high-statistics measurement of the relative branching fraction Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0). A 357 inverse fb data sample collected with the Belle detector…
