A recent publication has been highlighted as the “editors’ suggestion” in a high profile particle physics journal because of the importance of its research findings.

Together with collaborators from Argonne National Laboratory (USA) and the Institute For Particle Physics Phenomenology Durham (UK), Dr Christoph Englert of the University of Glasgow's Particle Physics Theory Group showed that the impact of the recently discovered Higgs boson reaches further than expected: Due to quantum interference, the Higgs boson can significantly alter the phenomenology of additional particles which are predicted by more fundamental theories than the Standard Model of Particle Physics, such as Supersymmetry, Higgs Portal Scenarios, or String Theories with large volume compactification. Such particles have a much larger mass than the Higgs boson itself, however, the calculations of Dr Englert and his collaborators demonstrate that interference between the Higgs boson and new particles can become large if the lifetimes of the latter particles are small. As a consequence, the discovery of such particles at the Large Hadron Collider, and a subsequent analysis of their impact on the broader landscape of Physics will crucially depend on the theoretical consistency of the underlying physics simulations provided by Dr Englert and his collaborators.
