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 ...

Observation of New Resonances in the Lambda(0)(b)pi(+)pi(-) System

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

We report the observation of a new structure in the Lambda(0)(b)pi(+)pi(- )spectrum using the full LHCb data set of pp collisions, corresponding to an integrated luminosity of 9 fb(-1), collected at root s = 7, 8, and 13 TeV. A study of the structure sugge ...

All that glitters is not gold: Recent progress of alternative counter electrodes for perovskite solar cells

Mohammad Khaja Nazeeruddin, Peng Gao, Xing Li

Although ultrahigh power conversion efficiency (PCE) up to 22.7% has been achieved by solution-processable perovskite solar cells (PSCs), there are still some obstacles that hinder the way of this promising photovoltaic technology to its commercialization. ...

Particle-Based Numerical Manifold Method to Model Dynamic Fracture Process in Rock Blasting

Jian Zhao, Qianbing Zhang, Xing Li

A particle-based numerical manifold method (PNMM) is developed to investigate rock fracturing behavior under dynamic loading. The basic idea of PNMM is to represent the microstructure of rock with a group of particles and to simulate the macroscopic behavi ...

Consequences of the Thermal Transient on the Evolution of the Damaged Zone Around a Repository for Heat-Emitting High-Level Radioactive Waste in a Clay Formation: a Performance Assessment Perspective

Vincent Labiouse, Xing Li, Li Yu

A proper evaluation of the perturbations of the host rock induced by the excavation and the emplacement of exothermic wastes is essential for the assessment of the long-term safety of high-level radioactive waste disposals in clay formations. The impact of ...

Numerical Simulation of the Rock SHPB Test with a Special Shape Striker Based on the Discrete Element Method

Yang Zou, Xing Li

A split Hopkinson pressure bar system with a special shape striker has been suggested as the test method by the International Society for Rock Mechanics (ISRM) to determine the dynamic characteristics of rock materials. In order to further verify this test ...
