Measurement of cos 2 beta in B-0 -> D((*))h(0) with D -> K-S(0)pi(+) pi(-) decays by a combined time-dependent Dalitz plot analysis of BABAR and Belle data

Olivier Schneider, Roberto Gargiani, Yiming Li, Mingkui Wang, Mithilesh Nayak, Chao Wang, Gaétan Charles Antoine Giriat, Tagir Aushev, Greig Alan Cowan, Sun Hee Kim

We report measurements of sin 2 beta and cos 2 beta using a time-dependent Dalitz plot analysis of B-0 -> D((*))h(0) with D -> K-S(0)pi(+)pi(-) decays, where the light unflavored and neutral hadron h(0) is a pi(0),eta, or omega meson. The analysis uses a c ...

Search for the rare decay of B+ -> l(+)nu e gamma with improved hadronic tagging

Olivier Schneider, Roberto Gargiani, Yiming Li, Mingkui Wang, Mithilesh Nayak, Chao Wang, Gaétan Charles Antoine Giriat, Sun Hee Kim, Tagir Aushev, Seyed Sina Mirrazavi Salehian

We present the result of the search for the rare B meson decay of B+ -> l(+)nu e gamma with l = e, mu. For the search the full data set recorded by the Belle experiment of 711 fb(-1) integrated luminosity near the Upsilon(4S) resonance is used. Signal cand ...

First Evidence for cos 2 beta > 0 and Resolution of the Cabibbo-Kobayashi-Maskawa Quark-Mixing Unitarity Triangle Ambiguity

Olivier Schneider, Roberto Gargiani, Yiming Li, Mingkui Wang, Mithilesh Nayak, Gaétan Charles Antoine Giriat, Chao Wang, Tagir Aushev, Greig Alan Cowan, Sun Hee Kim

We present first evidence that the cosine of the CP-violating weak phase 2 beta is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B-0 -> ...

Measurement of the decays Lambda c -> Sigma pi pi at Belle

Olivier Schneider, Yiming Li, Roberto Gargiani, Mingkui Wang, Gaétan Charles Antoine Giriat, Sun Hee Kim, Chao Wang, Tagir Aushev, Tara Nanut, Seyed Sina Mirrazavi Salehian

We report measurements of the branching fractions of the decays Lambda(+)(c) -> Sigma(+)pi(-)pi(+), Lambda(+)(c) -> Sigma(0)pi(+)pi(0) and Lambda(+)(c) -> Sigma(+)pi(0)pi(0) relative to the reference channel Lambda(+)(c) -> pK(-)p(+). The analysis is based ...

Measurement of the branching fraction and time-dependent CP asymmetry for B-0 -> J/psi pi(0) decays

Olivier Schneider, Yiming Li, Roberto Gargiani, Mingkui Wang, Mithilesh Nayak, Chao Wang, Gaétan Charles Antoine Giriat, Sun Hee Kim, Tagir Aushev, Arnaud Michel Gelb

We measure the branching fraction and time-dependent CP-violating asymmetry for B-0 -> /psi pi(0) decays using a data sample of 711 fb(-1) collected on the Gamma(4S) resonance by the Belle experiment running at the KEKB e(+)e(-) collider. The branching fra ...

Search for the lepton-flavor-violating decay B-0 -> K-*0 mu(+/-)e(-/+)

Olivier Schneider, Yiming Li, Roberto Gargiani, Gaétan Charles Antoine Giriat, Mingkui Wang, Chao Wang, Sun Hee Kim, Tagir Aushev, Tara Nanut, Chang-Hyun Park

We have searched for the lepton-flavor-violating decay B-0 -> K-*0 mu(+/-)e(-/+) using a data sample of 711 fb(-1) that contains 772 x 10(6) B (B) over bar pairs. The data were collected near the Upsilon(4S) resonance with the Belle detector at the KEKB as ...

Association of brain amyloidosis with pro-inflammatory gut bacterial taxa and peripheral inflammation markers in cognitively impaired elderly

Tristan Bolmont, Taoufiq Harach

The pathway leading from amyloid-b deposition to cognitive impairment is believed to be a cornerstone of the pathogenesis of Alzheimer's disease (AD). However, what drives amyloid buildup in sporadic nongenetic cases of AD is still unknown. AD brains featu ...

Reduction of Abeta amyloid pathology in APPPS1 transgenic mice in the absence of gut microbiota

Theo Lasser, Tristan Bolmont, Taoufiq Harach, Nicolas Jean Marc Antoine Duthilleul

Alzheimer’s disease is the most common form of dementia in the western world, however there is no cure available for this devastating neurodegenerative disorder. Despite clinical and experimental evidence implicating the intestinal microbiota in a number o ...

Administrations of human adult ischemia-tolerant mesenchymal stem cells and factors reduce amyloid beta pathology in a mouse model of Alzheimer's disease

Theo Lasser, Tristan Bolmont, Taoufiq Harach, Fabien Louis Claude Robert Jammes, Nicolas Jean Marc Antoine Duthilleul, Valentin Laurent Herbert Zufferey

The impact of human adult ischemia-tolerant mesenchymal stem cells (hMSCs) and factors (stem cell factors) on cerebral amyloid beta (Aβ) pathology was investigated in a mouse model of Alzheimer's disease (AD). To this end, hMSCs were administered intraveno ...
