 +  * [[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.
