  We document the activities performed during the second MadAnalysis 5 workshop
on LHC recasting, that was organised in KIAS (Seoul, Korea) on February 12-20,
2020. We detail the implementation of 12 new ATLAS and CMS searches in the
MadAnalysis 5 Public Analysis Database, and the associated validation
procedures. Those searches probe the production of extra gauge and
scalar/pseudoscalar bosons, supersymmetry, seesaw models and deviations from
the Standard Model in four-top production.
