报告时间更正
今天上午报告时,Dr. A. Beckwith为与Baker教授所做的报告相对应,临时调整了报告的顺序,原定明天的报告<Neutrino physics, dark matter & relic gravitational waves and the Li-Baker HFGW detector >今天已经做了,而原来安排的<LHC inverse problem, and how its resolution may permit us to obtain realistic Dark Matter candidates?> 将在明天做.
请对报告内容感兴趣的老师和同学们注意!
以下为更正后的报告安排
时间:2008-10-21,下午15:00-16:00
地点:数理学院(309)311学术讨论室
报告人: R.M. Baker教授
报告题目: <Radiation Pattern for a Multiple-Element HFGW Generator>
内容简介:We utilize the result of Romero and Dehnen (1981) and Dehnen and Romero-Borja (2003) for an increase in HFGW flux proportional to N2. This result is employed to compute the half-power-point angle, idealized radiation cap area and the HFGW flux/power-of-a-single-radiation-element at a distance of several wavelengths away, for example one meter from the end of a linear and a double-helical array in Wm-2 as a function of N. As well as an IR-energized ring. It is described at a distance far enough from the generator that it is beyond the conventional diffraction limit of a beam’s radiation-pattern cap area. It is found that the HFGW flux calculated is small, but that the Li-Baker detector may be capable of sensing the HFGWs generated in a laboratory setting.

报告题目: <LHC inverse problem, and how its resolution may permit us to obtain realistic Dark Matter candidates?>
内容简介: How the LHC can enable us to get realistic dark matter (DM) candidates? We wish to state the general LHC inverse problem. Given a finite set of measurements with finite resolution, how does one map back to the underlying theory for a new physics phenomena? We will for the sake of convenience confine our remarks to DM candidates, and their linkage to parameter space issues.
