Search for the rare decay B+ -> mu(+) mu(-) mu(+)nu(mu)

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, François Fleuret, John Martin Kolinski, Luca Pescatore

A search for the rare leptonic decay B +. mu + mu - mu +.mu is performed using proton- proton collision data corresponding to an integrated luminosity of 4.7 fb - 1 collected by the LHCb experiment. The search is carried out in the region where the lowest ...

Measurement of CP observables in the process B-0 -> DK*0 with two- and four-body D decays

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Tatsuya Nakada, Christoph Frei, Achille Mauri, Frédéric Blanc, Michel De Cian, Luca Pescatore

Measurements of CP observables in B-0 -> DK0 decays are presented, where D represents a superposition of D-0 and D0 states. The D meson is reconstructed in the two-body final states K+pi(-), pi K-+(-), K+K- and pi(+)pi(-), and, for the first time, in the f ...

Study of the B-0 (770)degrees K-*(892)(0) decay with an amplitude analysis of B-0 ((+-))(K+pi(-)) decays

Olivier Schneider, Guido Haefeli, Yiming Li, Christoph Frei, Aurelio Bay, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Luca Pescatore, François Fleuret

An amplitude analysis of B-0 ((+-))(K+-) decays is performed in the two-body invariant mass regions 300 < m((+-)) < 1100 MeV/c(2), accounting for the (0), , f(0)(500), f(0)(980) and f(0)(1370) resonances, and 750 < m(K+-) < 1200 MeV/c(2), which is dominate ...

Measurement of the CP-violating phase phi(s) from B-s(0) -> J/psi pi(+)pi(-) decays in 13 TeV pp collisions

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, Mingkui Wang, Mercedes Hannelore Rittmann-Frank, Michael Thompson McCann

Decays of B-s(0) and (B) over bar (0)(s) mesons into J/psi pi(+)pi(-) final states are studied in a data sample corresponding to 1.9 fb(-1) of integrated luminosity collected with the LHCb detector in 13 TeV pp collisions. A time-dependent amplitude analys ...

Updated measurement of time-dependent CP-violating observables in B-s(0) -> J/psi K+K- decays

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, François Fleuret, Michael Thompson McCann, Michel De Cian

The decay-time-dependent CP asymmetry in B0 s. J/. K + K-decays is measured using proton-proton collision data, corresponding to an integrated luminosity of 1.9 fb-1, collected with the LHCb detector at a centre-ofmass energy of 13 TeV in 2015 and 2016. Us ...

Measurement of the branching fractions of the decays D+ -> K-K+K+, D+ -> pi-pi(+) K+ and D-s(+) -> pi-K+K+

Olivier Schneider, Yiming Li, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Elena Graverini, Sergi Aguacil Moreno

The branching fractions of the doubly Cabibbo-suppressed decays D+ ! K, D+ ! and D+ s ! are measured using the decays D+ ! K and D+ s ! K as normalisation channels. The measurements are performed using proton-proton collision data collected with the LHCb d ...

Measurement of CP-Violating and Mixing-Induced Observables in B-s(0) -> phi gamma Decays

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, François Fleuret, Jorge Miguel Dias Almeida Rodrigues Soares, Michel De Cian

A time-dependent analysis of the B-s(0) -> phi gamma decay rate is performed to determine the CP -violating observables S-phi gamma and C-phi gamma and the mixing-induced observable A(phi gamma)(Delta). The measurement is based on a sample of pp collision ...

Search for CP violation using triple product asymmetries in Lambda(0)(b) -> pK(-) pi(+) pi(-), Lambda(0)(b) -> pK(-) K+ K- and Xi(0)(b) -> pK(-) K- pi(+) decays

Olivier Schneider, Yiming Li, Guido Haefeli, Aurelio Bay, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Christoph Frei, Luca Pescatore, Elena Graverini

A search for CP and P violation using triple- product asymmetries is performed with Lambda(0)(b) -> pK(-) pi(+) pi(-), Lambda(0)(b) -> pK(-) K+ K- and Xi(0)(b) -> pK(-) K- pi(+) decays. The data sample corresponds to integrated luminosities of 1.0 fb(-1) a ...

The climate of Europe during the Holocene: a gridded pollen-based reconstruction and its multi-proxy evaluation

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins, Achille Mauri

We present a new gridded climate reconstruction for Europe for the last 12,000 years based on pollen data. The reconstruction is an update of Davis et al. (2003) using the same methodology, but with a greatly expanded fossil and surface-sample dataset and ...

The influence of atmospheric circulation on the mid-Holocene climate of Europe: a data-model comparison

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins, Achille Mauri

The atmospheric circulation is a key area of uncertainty in climate model simulations of future climate change, especially in mid-latitude regions such as Europe where atmospheric dynamics have a significant role in climate variability. It has been propose ...
