标题： Infrared Issues in Graviton Higgs Theory

摘要： 我们研究了在闵可夫斯基背景下的最小耦合引力子希格斯理论中有效势的一环红外行为。 一环Coleman Weinberg有效势的引力类似物结果为复数，虚部表明存在红外不稳定性。 这种不稳定性归因于常数希格斯场下引力子传播子中的快子极点。 研究了这种行为的物理意义。 我们还讨论了耦合希格斯场的规范理论与引力子希格斯理论之间的物理差异。 显示英文摘要

摘要： We investigate the one-loop infrared behaviour of the effective potential in minimally coupled graviton Higgs theory in Minkowski background. The gravitational analogue of one loop Coleman Weinberg effective potential turns out to be complex, the imaginary part indicating an infrared instability. This instability is traced to a tachyonic pole in the graviton propagator for constant Higgs fields. Physical implications of this behaviour are studied. We also discuss physical differences between gauge theories coupled to Higgs fields and graviton Higgs theory.
