Interference effects in heavy W'-boson searches at the LHC

Understand

Interference effects are widely neglected in searches for new physics.

• This is the case in recent publications on searches for W'-bosons using leptonic final states.
• We examine the effects of interference on distributions frequently used to determine mass limits for possible W'-bosons and show that there are important qualitative effects on the behaviour of the new physics signal.
• There are two main consequences.
