Search for CP violation in Xi(-)(b) -> pK(-)K(-) decays

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

A search for CP violation in charmless three-body Xi(-)(b) -> pK(-)K(-) decays is performed using pp collision data recorded with the LHCb detector, corresponding to integrated luminosities of 1 fb(-1) at a center-of-mass energy root S = 7 TeV, 2 fb(-1) at ...

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 ...

Experimental study of wakefields driven by a self-modulating proton bunch in plasma

Ambrogio Fasoli, Yiming Li, Ivo Furno, Patrick Blanchard, Alan Howling, Yanis Andrebe, Rémy Jacquier, Riccardo Agnello, Sun Hee Kim, Ishkhan Gorgisyan

We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growth and amplitude increase with increasing seed amplitude as well as with the ...

First observation of the decay B-0 -> D-0(D)over-bar(0)K(+)pi(-)

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

The first observation of the decay B-0 -> D-0(D) over bar K-0(+)pi(-) is reported using proton-proton collision data corresponding to an integrated luminosity of 4.7 fb(-1) collected by the LHCb experiment in 2011, 2012 and 2016. The measurement is perform ...

Experimental Observation of Plasma Wakefield Growth Driven by the Seeded Self-Modulation of a Proton Bunch

Gennady Plyushchev, Yiming Li, Sijie Liu, Michele Marin, Sun Hee Kim, Ishkhan Gorgisyan, Shuai Liu

We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of 2.1 x 10(14) and 7.7 x 10(14) electrons/cm(3). We show that these wakefields periodically defocus the proton bunch itself, consistently with t ...

Path to AWAKE: Evolution of the concept

Yiming Li, Hua Zhang, Gennady Plyushchev, Shuai Liu, Frank Zimmermann

This paper describes the conceptual steps in reaching the design of the AWAKE experiment currently under construction at CERN. We start with an introduction to plasma wakefield acceleration and the motivation for using proton drivers. We then describe the ...

AWAKE, The Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN

Yiming Li, Hua Zhang, Gennady Plyushchev, Shuai Liu

The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) aims at studying plasma wakefield generation and electron acceleration driven by proton bunches. It is a proof-of-principle R&D experiment at CERN and the world's first proton driv ...

Observation of the rare B-s(0)->mu(+)mu(-) decay from the combined analysis of CMS and LHCb data

Matthias Finger, Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Qian Wang, Frédéric Blanc, Yiming Li, Tatsuya Nakada, Varun Sharma

The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested experimentally. The probabilitie ...

Study of chi(cJ) decaying into phi K*(892)(K)over-bar

Qian Wang, Xin Chen, Jiannong Fang, Mingkui Wang, Zhirui Xu, Yi Zhang, Lei Zhang, Yixing Chen, Hua Zhang, Siyuan Wang

Using a data sample of 106 million psi(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays chi(cJ) -> phi(KSK +/-)-K-0 pi(-/+) and chi(cJ) -> phi K+K-pi(0) in the E1 radiative transiti ...
