The following EvtGen models have problems or are superseded by others and should probably be removed:
| Model | Description | Reason | LHCb DecFiles impact |
| EvtBHadronic | Attempt at implementing hadronic decay amplitudes | Experimental code that is not recommended to be used | None |
| EvtMultibody | Implements a crude Dalitz plot model using only simple Breit-Wigners | Unknown decay file parameter syntax and superseded by other working Dalitz (and 4-body) models | None |
| EvtMBreitWigner, EvtMHelAmp, EvtMNode, EvtMParticle, EvtMRes, EvtMTree and EvtMTrivialLS | Helper classes for EvtMultibody | Not needed after removal of EvtMultibody | None |
| EvtLambdaB2LambdaV | LambdaB to Lambda V, where V = J/psi, rho or omega (LHCb 2007) | Kinematic variables that divide by pT which is zero in the LambdaB frame; invariant mass distributions exponentially increase up to an upper threshold | None |
| EvtLb2Lll | LambdaB to Lambda ell ell | Superseded by the EvtRareLbToLll model | None |
| EvtVPHOtoV | Virtual photon to Vector | Not used in EvtModelReg | None |
| EvtVPHOtoVISR | Virtual photon to Vector gamma | Not used in EvtModelReg and appears to be superseded by EvtVPHOtoVISRHi (which is available) | None |
| EvtKstarstargamma | Kstar radiative decays | Code is broken and appears difficult to fix: see T178 | None |
| EvtbsToLLLL | Bs to 4 ell decays, ell = e or mu | Bug fix with lepton amplitude loop suggests there could be other problems: T160 | 2 files using BQTOLLLL |
| EvtbsToLLLLHyperCP | Bs to 4 ell decays HyperCP model, ell = e or mu, arXiv:1112.5230 | Model regularly fails accept/reject: T160 | 4 files using BQTOLLLLHYPERCP |
| Evtbs2llGammaISRFSR | Bs to gamma ell ell decays, ell = e or mu | Model regularly fails accept/reject: T160 | 13 files using BSTOGLLISRFSR |
| EvtPropSLPole | semi-leptonic decays | SLPOLE should be used in preference | None |
