摘要:

具有八个无质量基本费米子的SU(3)规范理论似乎在共形边界附近,是一个步行人工色的候选理论。沿着LatKMI合作使用HISQ费米子的一系列研究,S-参数和矢量衰变常数,这提供了重要的限制模型的电弱对称性破缺,计算该理论。使用不同的体积可以系统地研究有限体积效应。发现S参数对体积有很强的敏感性。

英文摘要:

SU(3) gauge theory with eight massless fundamental fermions seems to be near the conformal boundary, and is a candidate theory of walking technicolor. Along the series of study by LatKMI collaboration using HISQ fermions, S-parameter and vector decay constant, which provide important constraints in the model of electroweak symmetry breaking, are calculated for this theory. Use of various volumes allows a systematic investigation of finite volume effects. A strong sensitivity of the S-parameter to the volume is found.
