Study of decay mechanisms in B-→Λc+p̄π- decays and observation of low-mass structure in the Λc+p̄ system

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

Using a sample of 152×106 BB̄ pairs accumulated with the Belle detector at the KEKB e+e- collider, we study the decay mechanism of three-body charmed decay B-→Λc+p̄π-. The intermediate two-body decay B-→Σc(2455)0p̄ is observed for the first time with a bra ...

We report the observation of the flavor-changing neutral current process b→dγ using a sample of 386×106 B meson pairs accumulated by the Belle detector at the KEKB e+e- collider. We measure branching fractions for the exclusive modes B-→ρ-γ, B̄0→ρ0γ, and B ...

Early trafficking events of Mycobacterium ulcerans within Naucoris cimicoides

Stewart Cole

The severe skin-destructive disease caused by Mycobacterium ulcerans, named Buruli ulcer, is the third most important mycobacterial disease in humans after tuberculosis and leprosy. Recently we demonstrated that M. ulcerans could colonize the salivary glan ...

Immunogenicity of Mycobacterium ulcerans Hsp65 and protective efficacy of a Mycobacterium leprae Hsp65-based DNA vaccine against Buruli ulcer

Stewart Cole

Buruli ulcer, a disease caused by Mycobacterium ulcerans, is emerging as an increasingly important cause of morbidity throughout the world, for which surgery is the only efficient treatment to date. The aim of this work was to identify potential vaccine ca ...

Benzofuro[3,2-f][1]benzopyrans: a new class of antitubercular agents

Stewart Cole

Alkylation of 2-hydroxydibenzofuran with 3-chloro-3-methyl-1-butyne, followed by Claisen rearrangement, gave access to 3,3-dimethyl-3Hbenzofuro[3,2-f][1]-benzopyran. Several derivatives modified at the pyran 1,2-double bond were prepared, including the cor ...

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 ...

Measurement of the branching fraction, polarization, and CP asymmetry for B0→ρ+ρ- Decays, and determination of the cabibbo-kobayashi-maskawa phase 2

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

We have measured the branching fraction B, longitudinal polarization fraction fL, and CP asymmetry coefficients A and S for B0→ρ+ρ- decays with the Belle detector at the KEKB e+e- collider using 253fb-1 of data. We obtain B=[22.8±3.8(stat)-2.6+2.3(syst)]×1 ...

Evidence of the purely leptonic decay B-→τ-ν̄τ

Aurelio Bay, Stewart Cole, Tagir Aushev, Vladislav Balagura

We present the first evidence of the decay B-→τ-ν̄τ, using 414fb-1 of data collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Events are tagged by fully reconstructing one of the B mesons in hadronic modes ...
