A Web Survey for Facial Expressions Evaluation

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Gianluca Antonini

In the recent years, researchers have investigated several methods of facial expression analysis. Their interest has been to apply their algorithms to sets of images labelled by a restrained number of experts. In order to deal with the generalizability of ...

Study of the charmed baryonic decays B̄0→Σc++p̄π- and B̄0→Σc0p̄π+

Olivier Schneider, Stewart Cole, Mingkui Wang, Chao Wang, Tagir Aushev, Lei Zhang, Sun Hee Kim, Jing Li

We study the three-body charmed baryonic decays B̄0→Σ c++p̄π- and B̄0→Σc0p̄π+ in the four-body final state B̄0→Λc+p̄π+π-, using a data sample of 357fb-1 accumulated at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. ...

Measurement of inclusive Ds, D0, and J/ψ rates and determination of the Bs(*)B̄s(*) production fraction in bb̄ events at the Υ(5S) resonance

Olivier Schneider, Stewart Cole, Chao Wang, Tagir Aushev, Lei Zhang, Sun Hee Kim, Jing Li

The inclusive production of Ds, D0, and J/ψ mesons is studied using a 1.86fb-1 data sample collected on the Υ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The number of bb̄ events in this Υ(5S) data sample is determine ...

Observation of the decay B̄0→Ds+Λp̄

Olivier Schneider, Aurelio Bay, Stewart Cole, Chao Wang, Tagir Aushev, Vladislav Balagura

We report the first observation of the decay B̄0→Ds+Λ p̄ with a statistical significance of 6.6σ. We measure B(B̄0→Ds+Λp̄)=(2.9±0.7±0.5±0.4) ×10-5, where the first error is statistical, the second is systematic, and the third error comes from the uncertain ...

Search for lepton flavor violating τ- decays with a KS 0 meson

Olivier Schneider, Stewart Cole, Chao Wang, Tagir Aushev, Lei Zhang

We have searched for the lepton flavor violating decays τ- → ℓ- KS 0 (ℓ = e or μ), using a data sample of 281 fb-1 collected with the Belle detector at the KEKB e+ e- asymmetric-energy collider. No evidence for a signal was found in either of the decay mod ...

Signal Reconstruction from Multiple Unregistered Sets of Samples using Groebner Bases

Martin Vetterli, Luciano Sbaiz, Patrick Vandewalle

We present a new method for signal reconstruction from multiple sets of samples with unknown offsets. We rewrite the reconstruction problem as a set of polynomial equations in the unknown signal parameters and the offsets between the sets of samples. Then, ...

Search for the decay B0→γγ

Olivier Schneider, Aurelio Bay, Stewart Cole, Chao Wang, Tagir Aushev, Lei Zhang, Vladislav Balagura, Jean Wicht, Sun Hee Kim, Christian Jacoby

The rare decay B0→γγ is searched for in 104fb-1 of data, corresponding to 111×106BB̄ pairs, collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No evidence for the signal is found, and an upper limit of 6.2×10-7 at 90% confidence ...

Search for the Θ(1540)+ pentaquark using kaon secondary interactions at Belle

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

Using kaon secondary interactions in the material of the Belle detector, we search for both inclusive and exclusive production of the Θ(1540) +. We set an upper limit of 2.5% at the 90% C.L. on the ratio of the Θ(1540)+ to Λ(1520) inclusive production cros ...
