Measurement of exclusive ρ+ρ- production in mid-virtuality two-photon interactions and study of the γγ* → ρρ process at LEP

Eduardo Sanchez, Horst Vogel, Aurelio Bay, Jian Zhao, Liang Sun, Qian Wang, Zhirui Xu, Matthias Weber, Ji Hyun Kim, Werner Lustermann, Xiao Wang, Zheng Wang

Exclusive ρ+ρ- production in two-photon collisions between a quasi-real photon, γ, and a mid-virtuality photon, γ*, is studied with data collected at LEP at centre-of-mass energies 183 GeV≤√s≤209 GeV with a total integrated luminosity of 684.8 pb-1. The cr ...

Aurelio Bay, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Vladislav Balagura, Lei Zhang, Ji Hyun Kim, Jing Li

We present measurements of the branching fraction, the polarization parameters and CP-violating asymmetries in B0→D*+D *- decays using a 140 fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collid ...

Aurelio Bay, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Sanjeev Kumar, Lei Zhang, Jing Li

We present new measurements of CP-violation parameters in B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, and KS0π0 decays based on a sample of 275×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. ...

Measurement of the time-dependent CP-violating asymmetry in BO→KSOπOγ decays

Aurelio Bay, Sun Hee Kim, Tagir Aushev, Stewart Cole, Sanjeev Kumar, Jing Li

We present a new measurement of CP-violation parameters in B0→KS0π0γ decay based on a sample of 275×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One of the B mesons is fully reconstruct ...

Measurement of the wrong-sign decays D0→K+π-π0 and D0→K+π-π+π-, and search for CP violation

Aurelio Bay, Sun Hee Kim, Tagir Aushev, Jing Li

Using 281fb-1 of data from the Belle experiment recorded at or near the Υ(4S) resonance, we have measured the rates of the "wrong-sign" decays D0→K+π-π0 and D0→K+π-π+π- relative to those of the Cabibbo-favored decays D0→K-π+π0 and D0→K-π+π+π-. These wrong- ...

Measurement of γγ → pp̄ production at Belle

Aurelio Bay, Sun Hee Kim, Tagir Aushev, Stewart Cole, Sanjeev Kumar

A high precision study of the process γγ→pp̄ has been performed using a data sample of 89 fb-1 collected with the Belle detector at the KEKB e+e- collider. The cross section of pp̄ production has been measured at two-photon center-of-mass (c.m.) energies b ...

Measurement of the running of the electromagnetic coupling at large momentum-transfer at LEP

Eduardo Sanchez, Horst Vogel, Aurelio Bay, Jian Zhao, Liang Sun, Qian Wang, Zhirui Xu, Matthias Weber, Ji Hyun Kim, Werner Lustermann, Xiao Wang, Zheng Wang

The evolution of the electromagnetic coupling, α, in the momentum-transfer range 1800 GeV2 < -Q2 < 21600 GeV2 is studied with about 40 000 Bhabha-scattering events collected with the L3 detector at LEP at centre-of-mass energies √s = 189-209 GeV. The runni ...
