The latter are called gluons since they glue the quarks together to form hadrons. Like the quarks, these gluons seem to be confined permanently inside the hadrons. Evidence of ...

Large-Field Inflation - Naturalness and String Theory
... waves, it implies that inflation was driven by energy densities at the GUT scale MGU T ∼ 2 × 1016 GeV . This favors single-field chaotic inflation models. These models require transplanckian excursions of the inflaton, forcing one to address the UV completion of the theory. We use a benchmark 4d effe ...

Why “noncommutative common causes” don`t explain anything

The fact that C + C ⊥ = 1 in terms of operators does not imply that it makes no difference whether any of the “events” occur, or none. There is a difference between a physical situation ...
