# Impact of $$\mathcal {CP}$$CP-violating interference effects on MSSM Higgs searches

@article{Fuchs2018ImpactO, title={Impact of \$\$\mathcal \{CP\}\$\$CP-violating interference effects on MSSM Higgs searches}, author={Elina Fuchs and Georg Weiglein}, journal={The European Physical Journal C}, year={2018}, volume={78}, pages={1-19} }

Interference and mixing effects between neutral Higgs bosons in the MSSM with complex parameters are shown to have a significant impact on the interpretation of LHC searches for additional Higgs bosons. Complex MSSM parameters introduce mixing between the $$\mathcal {CP}$$CP-even and $$\mathcal {CP}$$CP-odd Higgs states h, H, A into the mass eigenstates $$h_1, h_2, h_3$$h1,h2,h3 and generate $$\mathcal {CP}$$CP-violating interference terms. Both effects are enhanced in the case of almost…
