Probing for extra top Yukawa couplings in light of the $t\overline{t}h$ (125) observation
/ Hou, WeiShu ; Kohda, Masaya ; Modak, Tanmoy
The observation of $t\overline{t}h\left(125\right)$ production at the Large Hadron Collider (LHC) is the first direct measurement of the top Yukawa coupling. [...]

Constraining a lighter exotic scalar via samesign top
/ Hou, WeiShu ; Kohda, Masaya ; Modak, Tanmoy
It was shown recently that, in two Higgs doublet models without Z2 symmetry, extra Yukawa couplings such as ρtc , ρtt can fuel enough CP violation for electroweak baryogenesis (EWBG). [...]

Unraveling the couplings of a DrellYan produced ${Z}^{\prime}$ with heavyflavor tagging
/ Hou, WeiShu ; Kohda, Masaya ; Modak, Tanmoy
Despite the current absence of newphysics signals at the LHC, a ${Z}^{\prime}$ boson with ${m}_{{Z}^{\prime}}\sim 100\text{}\text{}\mathrm{GeV}$ could still emerge via DrellYan (DY) production, $q\overline{q}\to {Z}^{\prime}\to {\mu}^{+}{\mu}^{}$, in the next few years. [...]

Electroweak baryogenesis driven by extra top Yukawa couplings
/ Fuyuto, Kaori ; Hou, WeiShu ; Senaha, Eibun
We study electroweak baryogenesis driven by the top quark in a general two Higgs doublet model with flavorchanging Yukawa couplings, keeping the Higgs potential CP invariant. [...]

Searching for new scalar bosons via tripletop signature in cg→tS0→ttt¯
/ Kohda, Masaya ; Modak, Tanmoy ; Hou, WeiShu
The alignment phenomenon, that the 125 GeV h0 boson so resembles the Standard Model Higgs boson, can be understood in a two Higgs doublet model without discrete symmetry. [...]

Correlating Bq0→μ+μ− and KL→π0νν¯ decays with four generations
/ Hou, WeiShu ; Kohda, Masaya ; Xu, Fanrong
The Bs→μ+μ− mode has finally been observed, albeit at rate 1.2 σ below Standard Model (SM) value, while the rarer Bd0→μ+μ− decay has central value close to 4 times SM expectation but with only 2.2 σ significance. [...]

Flavor changing heavy Higgs interactions at the LHC
/ Altunkaynak, Baris ; Hou, WeiShu ; Kao, Chung ; Kohda, Masaya ; et al
A general two Higgs doublet model (2HDM) is adopted to study the signature of flavor changing neutral Higgs (FCNH) decay ϕ0→tc¯+t¯c , where ϕ0 could be a CPeven scalar ( H0 ) or a CPodd pseudoscalar ( A0 ). [...]
