چکیده
|
Run 2 lhc data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 gev. we analyse the data in terms of a new boson, extracting information on its properties and exploring theoretical interpretations. scenarios covered include a narrow resonance and, as preliminary indications suggest, a wider resonance. if the width indications persist, the new particle is likely to belong to a strongly-interacting sector. we also show how compatibility between run 1 and run 2 data is improved by postulating the existence of an additional heavy particle, whose decays are possibly related to dark matter.
