The Born cross sections are measured for the first time processes $e^+e^-\to D_s^{*+}D_{s0}^*(2317)^- +c.c.$ and D_s^{*+}D_{s1}(2460)^- at center-of-mass energy $\sqrt{s}=$ 4.600~GeV, 4.612~GeV, 4.626~GeV, 4.640~GeV, 4.660~GeV, 4.68~GeV, 4.700~GeV, D_s^{*+}D_{s1}(2536)^- 4.680~GeV, using data samples collected with BESIII detector BEPCII collider. No structures observed in cross-section distrib...

A combined search for the Standard Model Higgs boson with the ATLAS detector at the LHC is presented. The data sets used correspond to integrated luminosities from 4:6 fb 1 to 4:9 fb 1 of protonproton collisions collected at ffiffi s p 1⁄4 7 TeV in 2011. The Higgs boson mass ranges of 111.4 GeV to 116.6 GeV, 119.4 GeV to 122.1 GeV, and 129.2 GeV to 541 GeVare excluded at the 95% confidence leve...

We present investigations on beam instabilities that have been observed at 2.0 GeV and 2.5 GeV in the PLS storage ring. Stored beam currents of 2.0 GeV in the ring has been mainly limited by coupled-bunch instabilities. We have investigated dependences of the coupled-bunch instabilities on betatron tune, chromaticity and rf cavity temperatures at 2.0 GeV. 450 mA beam could be stored at 2.0 GeV....

We study the energy dependence of the transverse momentum (pT) spectra for charged pions, protons and anti-protons for Au+Au collisions at √ sNN = 62.4 and 200 GeV. Data are presented at mid-rapidity (|y| < 0.5) for 0.2 < pT < 12 GeV/c. In the intermediate pT region (2 < pT < 6 GeV/c), the nuclear modification factor is higher at 62.4 GeV than at 200 GeV, while at higher pT (pT > 7 GeV/c) the m...

Preliminary results from the four LEP experiments using data collected at 189 GeV have shown no evidence for the Standard Model Higgs boson. The preliminary 95% confidence level lower limits on the SM Higgs boson mass from ALEPH, DELPHI, OPAL, and L3 are 90.4 GeV/c, 94.1 GeV/c, 95.5 GeV/c, and 95.2 GeV/c, respectively. When LEP finishes in the year 2000, each experiment expects to collect 200 p...

In a general supersymmetric standard model there is an upper bound m h on the tree level mass of the CP = +1 lightest Higgs boson which depends on the electroweak scale, tan β and the gauge and Yukawa couplings of the theory. When radiative corrections are included, the allowed region in the (m h , m t) plane depends on the scale Λ, below which the theory remains perturbative, and the supersymm...
