+ | **Literature**: | ||
+ | **__Light A/H__**: | ||
+ | * [[http://arxiv.org/abs/1412.3385]]: A detailed analysis of the 2HDM allowed region for a light A0 (20 GeV < m_A0 < 60 GeV), both in TypeI and TypeII. It also has a discussion of detection prospects in bbA0 and gg->A0 for "aligment" and "wrong-sign" scenarios, showing that in particular for TypeII the "wrong-sign" can be completely explored with bbA0. | ||

* [[http://cds.cern.ch/record/2014119]]: CMS has recently carried on a search of A0 -> Z H0 / H0 -> Z A0 in ll bb, ll tautau final states. This search constraints values of tan_beta up to 4 for some (m_A0, m_H0) values with a sizable splitting. | * [[http://cds.cern.ch/record/2014119]]: CMS has recently carried on a search of A0 -> Z H0 / H0 -> Z A0 in ll bb, ll tautau final states.

* [[http://arxiv.org/abs/1405.5537]]: A physical motivation for a large mass splitting m_A0 - m_H0 ~ 200-300 GeV and the search for A0 -> Z H0 at LHC is provided: this large splitting leads to a strong EW phase transition in the early universe, which could be responsible for the generation of the observed matter-antimatter asymmetry via EW baryogenesis.

+ | * [[http://arxiv.org/abs/1208.2788]] Bounds on m_H+ from b -> s gamma, both for Type I and Type II. They show that for Type II, the bound is particularly strong (m_H+ > 380 GeV) and tan_beta independent. | ||
