- Assume light A0 scenario for 2HDM (m_A0 < 100 GeV, e.g. [[http://arxiv.org/abs/1412.3385]]). For TypeII 2HDM, a large splitting m_H0 - m_A0 ~ 200-300 GeV is required. For TypeI 2HDM, sizable m_H0 - m_A0 is not required but perfectly possible. In both cases, g g -> H0 -> Z A0 -> ll bb could probe this scenario for low tan_beta (< 5) as a complementary search to bbA0 ([[2015:groups:higgs:morehiggs:lowmassa]]). | - Assume light A0 scenario for 2HDM (m_A0 < 100 GeV, e.g. [[http://arxiv.org/abs/1412.3385]]).
