According to the Unruh effect, that observer detects the Minkowski vacuum as a thermal bath at a temperature proportional to the proper acceleration a. Then we show that (in a certain large N limit) when the acceleration is bigger than the critical value a_(c) = 4πv (where v is the Higgs vacuum expectation value), the electroweak SU(2)L × U(1)_(Y) gauge symmetry is restored and all elementary particles become massless. In addition, even observers with a ˂ a_(c) can see this symmetry restoration in the region close to the Rindler horizon. eng open access Brout-Englert-Higgs mechanism for accelerating observers journal article
