  3. 719. $H\to b\overline{b}j$ at next-to-next-to-leading order accuracy

    parallel talk

    We present the calculation of the process $H\to b\overline{b}j$ at next-to-next-to-leading order (NNLO) accuracy. We consider contributions in which the Higgs boson couples directly to bottom quarks, i.e. our predictions are accurate to order $\mathcal{O}(\alpha_s^3 y_b^2)$. We compute the various components needed to construct the NNLO contribution, including an independent calculation of the...

  4. 762. N3LO predictions for Higgs to decay to bottom quarks
    Ciaran Williams (SUNY Buffalo)
    06/05/2019, 15:00
    parallel talk

    We present a fully-differential calculation of the H → bb decay at next-to-next- to-next-to-leading order (N3LO) accuracy. Our calculation considers diagrams in which the Higgs boson couples directly to the bottom quarks. In order to regulate the infrared divergences present at this order we use the Projection-to-Born technique coupled with N-jettiness slicing. After validating our methodology...

  5. 808. Charm-quark Yukawa Coupling in $h\rightarrow c\bar{c}\gamma$ at LHC
    Xing Wang (University of Pittsburgh)
    06/05/2019, 15:15
    parallel talk

    It is extremely challenging to probe the charm-quark Yukawa coupling at hadron colliders primarily due to the large Standard Model (SM) background (including $h\to b\bar b$) and the lack of an effective trigger for the signal $h\to c\bar c$. We examine the feasibility of probing this coupling at the LHC via a Higgs radiative decay $h\rightarrow c\bar{c}\gamma$. The existence of an additional...

  6. 671. Probing the Higgs Yukawa coupling to the top quark at the LHC via single top+Higgs production
    Ya-Juan Zheng
    06/05/2019, 15:30
    parallel talk

    The conjoined production at the LHC of single top and Higgs boson via t-channel weak boson exchange is ideal to probe the top-quark Yukawa coupling, due to a delicate cancellation between the amplitudes with the htt and the hWW couplings. We find that the top quark is produced with 100% polarization in the leading order, and its quantum state is determined by the spin-vector direction in the...

  7. 745. Anatomy of the tthh Physics at HL-LHC
    LINGFENG LI (UC Davis)
    06/05/2019, 15:45
    parallel talk

    In this ongoing work, we study the phenomenology of Higgs pair production with a pair of top quarks ($pp\to t\bar{t}hh$) at the HL-LHC. Several final state/channels are simulated and evaluated with the help of multivariable analysis techniques. It turns out that the multi-$b$ + single lepton channel contributes the most to the signal significance, followed by the same-sign dilepton channel....
