希格斯机制存在吗?
Does the Higgs Mechanism Exist?
摘要:
本文探讨了标准模型的电弱规范理论中的自发对称性破缺概念的论元结构:即所谓的希格斯机制。正如通常所理解的,希格斯论证的目的是通过一个额外的场--希格斯场--的规范对称性的自发破缺来引入规范玻色子的质量。然而,希格斯机制的技术推导仅仅是通过以规范不变的方式变换希格斯拉格朗日量来重新调整自由度。这已经使人严重怀疑整个行动是否充分。我们将证明,由于规范变换不具有实的实例化,所以对希格斯机制的直接的本体解释是站不住脚的。此外,希格斯参数的解释价值将被严格审查。
英文摘要:
This paper explores the argument structure of the concept of spontaneous symmetry breaking in the electroweak gauge theory of the Standard Model: the so-called Higgs mechanism. As commonly understood, the Higgs argument is designed to introduce the masses of the gauge bosons by a spontaneous breaking of the gauge symmetry of an additional field, the Higgs field. The technical derivation of the Higgs mechanism, however, consists in a mere re-shuffling of degrees of freedom by transforming the Higgs Lagrangian in a gauge-invariant manner. This already raises serious doubts about the adequacy of the entire manoeuvre. It will be shown that no straightforward ontic interpretation of the Higgs mechanism is tenable since gauge transformations possess no real instantiations. In addition, the explanatory value of the Higgs argument will be critically examined.
