An overview of recent physics results from NSTX
The National Spherical Torus Experiment (NSTX) is currently being upgraded to operate at twice the toroidal field and plasma current (up to 1 T and 2 MA), with a second, more tangentially aimed neutral beam (NB) for current and rotation control, allowing for pulse lengths up to 5 s. Recent NSTX physics analyses have addressed topics that will allow NSTX-Upgrade to achieve the research goals cri...
متن کاملOverview of results from the National Spherical Torus Experiment (NSTX)
The mission of the National Spherical Torus Experiment (NSTX) is the demonstration of the physics basis required to extrapolate to the next steps for the spherical torus (ST), such as a plasma facing component test facility (NHTX) or an ST based component test facility (ST-CTF), and to support ITER. Key issues for the ST are transport, and steady state high β operation. To better understand ele...
متن کاملRecent b-physics results from OPAL
The most recent b-physics results from the OPAL experiment at LEP are reviewed. A measurement of semileptonic B meson decays to narrow orbitally-excited charm mesons is presented first, followed by a study of charm production in b-hadron decays. Here, B refers to B and B mesons and their charge conjugates, and b-hadron refers to the admixture of hadrons containing a b quark produced in electron...
متن کاملRecent Results on Flavor Physics from BABAR
We report an update to our previous measurement of the CKM element |Vub| using exclusive B → π`ν decays. In the charm sector we have performed a measurement of fDs using D + s → τ ντ decays, we have measured the mixing parameter yCP using the lifetime ratio 〈τKπ〉 〈τhh〉 in D decays, and we have also searched for CP violation using T-odd correlations in D decays to K+K−π+π−. Finally, in the tau s...
متن کاملRecent Beauty Physics Results from Argus
Recent results on B meson decays are reported from the ARGUS experiment, which operates at the DORIS II e+estorage ring at DESY. Evidence is presented for the first observation of an exclusive b-u decay in the channel B--) pop-v. A preliminary branching ratio of (1.13 f 0.36 f 0.26) x 10e3 is reported, from which the ratio IVUbl/lVcbl is calculated and found to be in agreement with inclusive me...
