论文摘要
我们研究了由额外底部的Yukawa耦合$ρ_{bb} $探索的前景，这是通过电动偶极矩（EDM）测量值和对撞机实验的一般两个HIGGS DoubleT模型。参数空间从125个GEV HIGGS $ H $ BOSON信号强度测量以及在大型强生对撞机（LHC）处获得有意义的约束。此外，我们表明，包含$ b \ tox_sγ$衰减的CP不对称性的不对称性将提供互补的探针。如果$ |ρ_{bb} | \ sim 0.15 $和$ 250〜 \ mbox {gev} \ lyseSim m_a \ lyseSim m_a \ sillsim 350 $ 350 $ gev，则可以通过$ bg \ ba \ to ba \ to ba \ to ba \ to Ba \ to Ba \ to Ba \ to Ba \ to Ba \ to Ba \ ba \ sim 350 $ gev，而其中$ | \ sim 350 $ gev，则可以通过$ bg \ to Ba \ ba \ to Ba \ ba $进程进行发现。对于$ m_a> 2 m_t $阈值，其中$ m_t $是顶级夸克质量，如果高光度LHC在高光度LHC上也可能会发现$ bg \ to ba \ to b t \ bar t $，如果额外的顶级Yukawa耦合$ |ρ_{ttt} | \ sim0.5 $，虽然可能会受到系统的影响。为了完整性，我们将$ gg \ to t \ bar t a \ t \ bar t b \ b $ b $，但发现它不希望。
We study the prospect of probing electroweak baryogenesis driven by an extra bottom Yukawa coupling $ρ_{bb}$ in a general two Higgs doublet model via electric dipole moment (EDM) measurements and at the collider experiments. The parameter space receives meaningful constraints from 125 GeV Higgs $h$ boson signal strength measurements as well as several heavy Higgs boson searches at the Large Hadron Collider (LHC). In addition, we show that the asymmetry of the CP asymmetry of inclusive $B\to X_s γ$ decay would provide complementary probe. A discovery is possible at the LHC via $bg\to bA \to b Z h$ process if $|ρ_{bb}|\sim 0.15$ and $250~\mbox{GeV}\lesssim m_A \lesssim 350$ GeV, where $A$ is CP odd scalar. For $m_A> 2 m_t$ threshold, where $m_t$ is the top quark mass, one may also discover $bg\to bA \to b t \bar t$ at the high luminosity LHC run if an extra top Yukawa coupling $|ρ_{tt}|\sim0.5$, though it may suffer from systematic uncertainties. For completeness we study $gg\to t \bar t A \to t \bar t b \bar b $ but find it not promising.
