Abstract
The resummed transverse momentum distribution of supersymmetric Higgs bosons produced through gluon fusion at NLO+NLL is presented, including the exact quark and squark mass dependences. Considering various MSSM scenarios, we compare our results to previous ones within the POWHEG approach. We analyze the impact of the bottom loop which becomes the dominant contribution to the gluon fusion cross section for a wide range of the parameter space for the pseudo-scalar and heavy Higgs.
Highlights
We focus on the gluon fusion process in the minimal supersymmetric SM (MSSM), but our calculation will be applicable in a general 2-Higgs doublet model5 (2HDM)
We are ready to present our results for the transverse momentum spectrum of MSSM Higgs bosons produced in gluon fusion through next-to-leading order (NLO)+NLL
In order to compare to other calculations, it may be useful to consider the ratio of the pT distribution which includes the full quark mass dependence to the result in the heavy-top limit
Summary
While the effect of the four lightest quarks as mediators of the gluon-Higgs coupling is negligible ( 1%) and usually omitted, the bottom quark contributes at the 5 − 10% level to the total cross section at next-to-leading order (NLO) [27, 28]. In the SM, the NNLO transverse momentum distribution of the Higgs produced via gluon fusion at pT > 0 has already been known for some time in the heavy-top limit [32,33,34].1. Transverse momentum resummation at leading logarithmic (LL) and next-to-LL (NLL) accuracy for the gluon fusion process in the heavy-top approximation has already been performed a long time ago [40,41,42]. Its application to the pT spectrum of the Higgs at NNLO+NNLL was implemented using the effective theory approach into the publicly available program HqT [43,44,45].2
