Study of the semileptonic decay $ {D}^0\to {\overline{K}}^0{\pi}^{-}{e}^{+}{\nu}_e $

We report an improved study of the semileptonic decay

{D}^0\to {\overline{K}}^0{\pi}^{-}{e}^{+}{\nu}_e

based on a sample of 7.9 fb − 1 of e + e − annihilation data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII ...

Partial Wave Analyses of Ψ(3686) → p(p)over-barπ0 and Ψ(3686) → p(p)over-barη

Yunxuan Song

Using a sample of (2712 +/- 14) x 10(6) psi(3686) events collected with the BESIII detector, we perform partial wave analyses of the decays psi(3686) -> p (p) over bar pi(0) and psi(3686) -> p (p) over bar eta. The branching fractions of psi(3686) -> p (p) ...

Observation of XcJ →3( K+ K- )

Yunxuan Song

By analyzing (27.12 +/- 0.14) x 10(8) Psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decay processes X-cJ -> 3( K+ K- ) (J = 0, 1, 2) are observed for the first time with statistical significances of 8.2 sigma, 8. ...

Self-phoretic oscillatory motion in a harmonic trap

Arthur Louis Mayeul Alexandre

We consider the motion of a harmonically trapped overdamped particle, which is submitted to a self-phoretic force, that is proportional to the gradient of a diffusive field for which the particle itself is the source. In agreement with existing results for ...

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

Olivier Schneider, Aurelio Bay, Guido Haefeli, Tatsuya Nakada, Frédéric Blanc, Lesya Shchutska, Mingkui Wang, François Fleuret, Chao Wang, Yi Zhang, Arnout Lodewijk M Beckers, Maxim Karpov, Liang Sun, Ian William Marison, Michael Thompson McCann, Valérie Jeanne Thérèse Renaudin-Schouler, Craig Matthew Smith, John Martin Kolinski, Simone Meloni, Achille Mauri, Basil Andrew Stansfield Davis, Chunmin Zhang, Mercedes Hannelore Rittmann-Frank, I-Chun Lin, Fabiano Colpo, Xiaoqiang Wang, Remy Jean Henry Albrecht, Xiaoqing Zhou, Marco Guarise, Yang Zou, Chia-Chun Chen, Huizhen Liu, Eliazar Rodriguez Garcia

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 ...

Anomaly-free scale symmetry and gravity

Mikhail Chapochnikov, Anna Tokareva

In this Letter, we address the question of whether the conformal invariance can be considered as a global symmetry of a theory of fundamental interactions. To describe Nature, this theory must contain a mechanism of spontaneous breaking of the scale symmet ...

Spin, Charge, and ?-Spin Separation in One-Dimensional Photodoped Mott Insulators

Philipp Georg Werner Seeberger

We show that effectively cold metastable states in one-dimensional photodoped Mott insulators described by the extended Hubbard model exhibit spin, charge, and q-spin separation. Their wave functions in the large on-site Coulomb interaction limit can be ex ...

A concept for the extraction of the most refractory elements at CERN-ISOLDE as carbonyl complex ions

João Pedro Fernandes Pinto Ramos

We introduce a novel thick-target concept tailored to the extraction of refractory 4d and 5d transition metal radionuclides of molybdenum, technetium, ruthenium and tungsten for radioactive ion beam production. Despite the more than 60-year old history of ...

Observation of a New Excited D^+_s Meson in B^0 \rightarrow D^- D^+ K^+ \pi^- Decays

Lesya Shchutska

Using pp collision data corresponding to an integrated luminosity of 5.4 fb−1 collected with the LHCb detector at a center-of-mass energy of 13 TeV, the B0→D−D+K+π− decay is studied. A new excited D+s meson is observed decaying into the D+K+π− final state ...

Lightning to tall structures: Characterization, Modeling and Protection

Antonio Sunjerga

Lightning physics is highly multidisciplinary, involving areas such as plasma physics, electrical engineering, meteorology, thermodynamics and particle physics. Upward lightning is a special type of lightning initiated from tall structures that has attract ...

Comparison of high density and nitrogen seeded detachment using SOLPS-ITER simulations of the tokamak a configuration variable

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh, Mirko Wensing, Hugo De Oliveira, Lorenzo Martinelli

First of a kind SOLPS-ITER simulations on tokamak a configuration variable (TCV) that include nitrogen have been performed to model recent nitrogen seeded detachment experiments. Based on spectroscopic measurements, a nitrogen recycling coefficient R-p(N) ...

Nitrogen-seeded divertor detachment in TCV L-mode plasmas

Basil Duval, Benoît Labit, Holger Reimerdes, Christian Gabriel Theiler, Roberto Maurizio, Cedric Kar-Wai Tsui, Hugo De Oliveira, Kevin Henricus Annemarie Verhaegh

Most of the detachment experiments done to date on the tokamak a configuration variable (TCV), both in standard and alternative divertor geometries, focused on L-mode integrated core density ramps. In view of extending these studies to high-power, high-con ...
