The abstract, sentence by sentence
If a leptoquark is produced at HERA as a narrow resonance, various effects tend to broaden the measurable mass distribution considerably. These effects are discussed here, with special emphasis on initial- and final-state QCD radiation. A proper understanding is important to assess the significance of data and to devise strategies for better mass reconstruction.

The paper
Original abstract
If a leptoquark is produced at HERA as a narrow resonance, various effects tend to broaden the measurable mass distribution considerably. These effects are discussed here, with special emphasis on initial- and final-state QCD radiation. A proper understanding is important to assess the significance of data and to devise strategies for better mass reconstruction.

Heavy long-lived particles (LLP) are predicted in a range of extensions of the Standard Model (SM) [ref] . $R$-parity-conserving supersymmetry (SUSY) [ref] models, such as split SUSY [ref] , gauge-mediated SUSY breaking (GMSB) [ref] and [ref] , as well as other scenarios such as universal extra dimensions [ref] and leptoquark extensions [ref] , allow for a variety of LLP states stable enough to be directly identified by the ATLAS detector.

Other proposed BSM scenarios that could result in long-lived particle decays into at least one muon include long-lived lepto-quarks [ref] , long-lived BSM particles appearing in decays of Higgs bosons [ref] , scenarios with right-handed neutrinos with Majorana masses below the electroweak scale [ref] and RPV scenarios with a long-lived electroweakino LSP decaying through a virtual scalar muon and a $_2jk$ coupling [ref] .
