LOW-ENERGY,HIGH-CURRENT ELECTRON BEAM TRANSPORTATION THROUGH...

Observation of e^+e^-→D_s^+■^((*)0)K^- and study of the P-wave D_s mesons

The 17th International Conference on High-Power Particle Beams

作者： Grigory e.Ozur vladimir P.Grigoriev Tamara v.Koval evgeny v.Nefyodtsev Institute of High Current electronics Siberian BranchRussian Academy of Sciences 2/3Academichesky Ave.Tomsk634055Russia Institute Cybernetic Centre Tomsk Polytechnic University84Sovetskaya Str.634034Russia Institute of High Current electronics Siberian BranchRussian Academy of Sciences 2/3Academichesky Ave.Tomsk634055Russia

＜正＞The process of high-current,low-energy electron beam transportation through a plasma channel in a guide magnetic field has been studied experimentally and by the use of computer *** has been shown that the decrease of the beam current amplitude with the length of the drift channel as well as the transformation of the beam energy distribution via its cross section may be explained by incomplete neutralization of the beam space charge at the stage of beam current rising.

Studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BeSIII detector at s^(1/2)=4.600 Gev. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) Mev/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)Mev, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) Mev/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) Mev. The spin-parity of the D_(s2)~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 Gev, and upper limits at the 90% confidence level on the cross sections are determined.

The most significant part of Wade Area Augmentation System (WAAS) integrity consists of the User Differential Range error (UDRe) and the Grid Ionospheric vertical error (GIve). WAAS solutions are not completely appropriate to determine the GIve term within the entire coverage zone taking in account real irregular structure of the ionosphere. It leads to the larger confidence bounding terms and lower expected positioning availability in comparison to the reality under geomagnetic storm conditions and system outages. Thus a question arises: is the basic WAAS concept appropriate to provide the same efficiency of the integrity monitoring for both “global differential correction”(i.e. clock, ephemeris et al.) and “local differential correction”(i.e. ionosphrere, troposhpere and multipath)? The aim of this paper is to compare official WAAS integrity monitoring reports and real positioning quality in US coverage zone (CONUS) and Canada area under geomagnetic storm con-ditions and system outages. In this research we are interested in compari-son between real GPS positioning quality based on single-frequency C/A ranging mode and HAL (vAL) values which correspond to the LP, LPv and LPv200 requirements. Significant mismatch of the information be-tween WAAS integrity data and real positioning quality was unfolded as a result of this comparison under geomagnetic storms and system outages on February 14, 2011 and June 22, 2015. Based on this result we think that in order to achieve high confidence of WAAS positioning availability alerts real ionospheric measurements within the wide area coverage zone must be involved instead of the WAAS GIve values. The better way to realize this idea is to combine WAAS solutions to derive “global differential cor-rections” and LAAS solutions to derive “local differential corrections”.

There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BeSⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BeSⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BeSⅢ during the remaining operation period of BePCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BePCⅡ to higher luminosity.
