In this last reference system we use the Unruh effect, where the proton sees a bath of thermal particles at the temperature  T = a / 2 &#960;, where  a is proton&#8217;s acceleration. Analytical results agree, thus giving a simpler example where the Unruh effect is necessary to keep the consistency between inertial and Rindler frame calculations of a physical observable.]]></p></abstract>
