论文摘要
我们检查了HMSSM内部沉重中性的Susy Higgs Bosons pp-> H，\ a->τ\Barτ的生产和衰变，并与可能更合理的自然超对称方案进行比较，将M_H^{125}（{\ rm nat}）（{\ rm nat}）（允许自然解释）for M__} M_ {W，Z，H} \ SIM 100 GEV，同时维护M_H \ Simeq 125 GEV。我们根据γ，z->τ\barτ，t \ bar {t}和矢量玻色子对生产VV的各种标准模型背景评估信号。我们将背对背（BTB）TAU的横向质量方法与ditau质量峰M_ {ττ}方法相结合，作为我们的信号通道。该技术最终可以增强仅使用BTB信号通道的标准技术的信号意义。我们在M_A中评估了95％Cl排除和5σDiscovery触手可及的目前LHC的\tanβPlane，具有139 fb^{ - 1}，以300 fb^{ - 1}和高光度LHC（HL-LHC）的300 fb^{ - 1}的3000 fb^{ - 1 fb^{ - 1}的集成亮度的亮度。对于\tanβ= 10，排除限制分别为m_a \ sim 1、1.1和1.4 TEV。可以将这些与从弦乐景观进行统计分析收集的M_A值的范围进行比较，其中M_A可以范围为〜8 TEV。
We examine production and decay of heavy neutral SUSY Higgs bosons pp-> H,\ A -> τ\barτ within the hMSSM and compare against a perhaps more plausible natural supersymmetry scenario dubbed m_h^{125}({\rm nat}) which allows for a natural explanation for m_{weak}\simeq m_{W,Z,h}\sim 100 GeV while maintaining m_h\simeq 125 GeV. We evaluate signal against various Standard Model backgrounds from γ,Z ->τ\barτ, t\bar{t} and vector boson pair production VV. We combine the transverse mass method for back-to-back (BtB) taus along with the ditau mass peak m_{ττ} method for acollinear taus as our signal channels. This technique ultimately gives a boost to the signal significance over the standard technique of using just the BtB signal channel. We evaluate both the 95% CL exclusion and 5σdiscovery reach in the m_A vs. \tanβplane for present LHC with 139 fb^{-1}, Run 3 with 300 fb^{-1} and high luminosity LHC (HL-LHC) with 3000 fb^{-1} of integrated luminosity. For \tanβ=10, the exclusion limits range up to m_A\sim 1, 1.1 and 1.4 TeV, respectively. These may be compared to the range of m_A values gleaned from a statistical analysis of the string landscape wherein m_A can range up to ~8 TeV.
