Understanding JET-C quiescent phases with edge harmonic magnetohydrodynamic activity and comparison with behaviour under ITER-like wall conditioning

Jonathan Graves, Wilfred Anthony Cooper, Daniele Brunetti, Alberto Mariani, Andreas Kleiner, Guillermo Bustos Ramirez

An analysis of edge localised mode-free (quiescent) H-mode discharges exhibiting edge harmonic magnetoydrodynamic activity in the JET-carbon wall machine is presented. It is observed that the otherwise quiescent pulses with multiple-n harmonic oscillations ...

Measurement of time-dependent CP violation in B-0 -> K-S(0)pi(0)pi(0) decays

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Tara Nanut, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Lei Li

We report a measurement of time-dependent CP violation in B-0 -> K-S(0)pi(0)pi(0) decays using a data sample of 772 x 10(6) B (B) over bar pairs collected by the Belle experiment running at the (sic)(4S) resonance at the KEKB e(+)e(-) collider. This decay ...

Observation of the Lambda(0)(b) -> Lambda phi decay

Jian Wang, Olivier Schneider, Yiming Li, Yi Zhang, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Luca Pescatore, François Fleuret, Elena Graverini, Chitsanu Khurewathanakul, Renato Quagliani, Maria Vieites Diaz, Federico Betti, Alessandro Mapelli, Zhirui Xu, Lei Zhang, Jessica Prisciandaro, Mark Tobin, Minh Tâm Tran, Niko Neufeld, Matthew Needham, Marc-Olivier Bettler, Greig Alan Cowan, Maurizio Martinelli, Donal Patrick Hill, Cédric Potterat, Liang Sun, Pietro Marino, Mirco Dorigo, Jean Wicht, Xiaoxue Han, Sebastiana Gianì, Liupan An, Federico Leo Redi, Ilya Komarov, Thibaud Humair, Maxime Schubiger, Hang Yin, Guido Andreassi, Bastien Luca Muster, Violaine Bellée, Olivier Göran Girard, Axel Kuonen, Hans Dijkstra, Gerhard Raven, Peter Clarke, Frédéric Teubert, Giovanni Carboni, Victor Coco, Adam Davis, Yu Zheng, Maxim Borisyak

The Lambda(0)(b) -> Lambda phi decay is observed using data corresponding to an integrated luminosity of 3.0 fb(-1) recorded by the LHCb experiment. The decay proceeds at leading order via a b -> ss loop transition and is therefore sens ...

First Observation of the Decay B(s2)(5840)(0) -> BK-+(-) and Studies of Excited B-s(0) Mesons

Jian Wang, Olivier Schneider, Yiming Li, Yi Zhang, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Christophe Salzmann, Lei Zhang, Jessica Prisciandaro, Mark Tobin, Minh Tâm Tran, Niko Neufeld, Matthew Needham, Marc-Olivier Bettler, Greig Alan Cowan, Maurizio Martinelli, Donal Patrick Hill, Cédric Potterat, Jean Wicht, Plamen Hristov Hopchev, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Barinjaka Rakotomiaramanana, Pierre Jaton, Joël Bressieux, Raluca Anca Muresan, Songmei Wu, Johan Luisier, Anne Keune, Vincent Fave, Hans Dijkstra, Gerhard Raven, Peter Clarke, Frédéric Teubert, Giovanni Carboni, Victor Coco, Wenyu Zhang

The properties of the orbitally excited (L =1) B-s(0) states are studied by using 1.0 fb(-1) of pp collisions at root s = 7 TeV collected with the LHCb detector. The first observation of the B-s2*(5840)(0) meson decaying to B*K-+(-) is reported, and the co ...

A novel design approach for a neutron measurement station for burnt fuel

Rakesh Chawla, Mathieu Hursin

The design and characterization of a passive neutron measurement station for highly burnt fuel has been undertaken at the Paul Scherrer Institute (PSI). The measurement station aims at the determination of the total neutron emission rate of full-length lig ...

Neutrino Analysis Of The 2010 September Crab Nebula Flare And Time-Integrated Constraints On Neutrino Emission From The Crab Using Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present the results of a search for high-energy muon neutrinos with the IceCube detector in coincidence with the Crab Nebula flare reported on 2010 September by various experiments. Due to the unusual flaring state of the otherwise steady source we perf ...

The dependence of the proton-triton thermo-nuclear fusion reaction rate on the temperature and total energy content of the high-energy proton distribution function

Duccio Testa, Christian Schlatter

The endothermic nuclear reaction between thermal tritons and high-energy protons can represent an important contribution to the total neutron yield in tokamak plasmas heated by radio-frequency waves, as the first JET experiments have demonstrated (see Mant ...

Proton-triton nuclear reaction in ICRF heated plasmas in JET

Duccio Testa, Christian Schlatter

Fast protons can react with tritons in an endothermic nuclear reaction which can act as a source of neutrons in magnetically confined fusion plasmas. We have performed an experiment to systematically study this reaction in low tritium concentration (approx ...

Evidence for the decay ∑+ → pμ+ μ-

Yixing Chen, Yu Fu

We report the first evidence for the decay ∑+ → pμ+ μ- from data taken by the HyperCP (E871) experiment at Fermilab. Based on three observed events, the branching ratio is B(∑+ → pμ+ μ-) = [8.6 -5.4 +6.6(stat) ± 5.5(syst)] × 10 -8. The narrow range of dimu ...
