Measurement of the Z boson production cross-section in proton-lead collisions at root(NN)-N-s=8.16 TeV

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, François Fleuret, John Martin Kolinski, Mingkui Wang, Chao Wang

This article presents the first measurement of the differential Z-boson production cross-section in the forward region using proton-lead collisions with the LHCb detector. The dataset was collected at a nucleon-nucleon centre-of-mass energy of root(NN)-N-s ...

Amplitude analysis of the D+-> pi(-)pi(+)pi(+) decay and measurement of the pi(-)pi(+) S-wave amplitude

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, François Fleuret, John Martin Kolinski, Mingkui Wang, Chao Wang

An amplitude analysis of the D+-> (-)pi(+)pi(+) decay is performed with a sample corresponding to 1.5 fb(-1) of integrated luminosity of pp collisions at a centre-of-mass energy root s = 8 TeV collected by the LHCb detector in 2012. The sample contains app ...

First branching fraction measurement of the suppressed decay Xi(0)(c) -> pi(-) Lambda(+)(c)

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

The Xi(0)(c) baryon is unstable and usually decays into charmless final states by the c -> sud transition. It can, however, also disintegrate into a pi(-) meson and a Lambda(+)(c) baryon via s quark decay or via cs -> dc weak scattering. The interplay betw ...

Palladium-Catalyzed Aminocarbonylation of Alkynes to Succinimides

Paul Joseph Dyson, Huizhen Liu, Pui Shan Genevieve Lau

Succinimide derivatives are useful building blocks for the synthesis of natural products and drugs. We describe an efficient route to succinimide derivatives comprising Pd(xantphos)Cl2-catalyzed aminocarbonylation of alkynes with aromatic or aliphatic amin ...

Cycloaddition of CO2 to epoxides catalyzed by imidazolium-based polymeric ionic liquids

Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Felix Daniel Bobbink, Ning Yan, Emilia Paunescu, Huizhen Liu, Hongbing Song, Saeideh Ghazali Esfahani

A series of cross-linked ionic polymers based on styrene-functionalized imidazolium salts with chloride, hexafluorophosphate, or tetrafluoroborate counter anions have been prepared and characterized using a range of analytical and spectroscopic techniques ...

One-Step Conversion of Cellobiose to C6-Alcohols Using a Ruthenium Nanocluster Catalyst

Paul Joseph Dyson, Ning Yan, Cheng Zhao, Huizhen Liu

The one-step conversion of cellulose to C6-alcs. via green and energy efficient approaches has, as far as we are aware, not been reported. Such a process presents a considerable challenge, the two key problems being (1) finding a suitable solvent that diss ...
