An optimal strategy for experimental searches in high-mass dilepton production at the LHC
Abstract
We present an optimal method for studying new physics effects in high-mass dilepton production at the LHC. This method relies on a reweighting procedure that is precise to the next-to-leading order in quantum chromodynamics. The only computationally expensive input required is a standard model pp→ V(*)→ℓ+ℓ- sample, with V=Z,γ*, generated at the same level of precision and with sufficient statistical coverage of the phase space at high invariant masses. The proposed method is suitable for any qq̅ℓ+ℓ- contact-interaction scenario, regardless of the assumed underlying structure and couplings. It is also ideal for searching for medium-to-large-width new neutral resonances produced in the s-channel, as changes to the input values for mass, coupling, or width can be easily implemented using the same initial generated samples.

The only computationally expensive input required is a standard model pp→ V^(*)→ℓ^+ℓ^- sample, with V=Z,γ^*, generated at the same level of precision and with sufficient statistical coverage of the phase space at high invariant masses.
