Therefore, it is necessary to have accurate predictions of these properties in models for new physics.

Afterwards, the main idea behind generic tools to study a large variety of models is summarised. Also some remarks about the validity of checks for perturbative unitarity, which are often applied for non-supersymmetric models, are given.","PeriodicalId":103336,"journal":{"name":"Proceedings of Prospects for Charged Higgs Discovery at Colliders — PoS(CHARGED2018)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134255312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
