Two-loop QCD amplitudes for production from boosted limit
Guoxing Wang, Tianya Xia, Li Lin Yang +1
The production of a Higgs boson in association with a top-antitop quark pair () holds significant importance in directly probing the top-quark Yukawa coupling, which is…
On the high-energy behavior of massive QCD amplitudes
Guoxing Wang, Tianya Xia, Li Lin Yang +1
In this note, we propose a factorization formula for gauge-theory scattering amplitudes up to two loops in the high-energy boosted limit. Our formula extends existing results in th…
Thrust distribution in Higgs decays up to the fifth logarithmic order
Wan-Li Ju, Yongqi Xu, Li Lin Yang +1
In this work, we extend the resummation for the thrust distribution in Higgs decays up to the fifth logarithmic order. We show that one needs the accurate values of the three-loop…
Two-loop infrared singularities in the production of a Higgs boson associated with a top-quark pair
Jiaqi Chen, Chichuan Ma, Guoxing Wang +2
The associated production of a Higgs boson and a top-quark pair is important for probing the Yukawa coupling of the top quark, and calls for better theoretical modeling. In this pa…
Invariant-mass distribution of top-quark pairs and top-quark mass determination
Wan-Li Ju, Guoxing Wang, Xing Wang +3
We investigate the invariant-mass distribution of top-quark pairs near the threshold, which has strong impact on the determination of the top-quark mass . We show that…
Mixed QCD-EW corrections for Higgs boson production at colliders
Yinqiang Gong, Zhao Li, Xiaofeng Xu +2
Since the discovery of the Higgs boson at the Large Hadron Collider, a future electron-position collider has been proposed for precisely studying its properties. We investigate the…
Resummed differential cross sections for top-quark pairs at the LHC
Benjamin D. Pecjak, Darren J. Scott, Xing Wang +1
We present state of the art resummation predictions for differential cross sections in top-quark pair production at the LHC. They are derived from a formalism which allows the simu…
One Bump or Two Peaks? The 750 GeV Diphoton Excess and Dark Matter with a Complex Mediator
Qing-Hong Cao, Yin-Qiang Gong, Xing Wang +2
We consider the possibility that the recently observed excess in the diphoton invariant mass spectrum around 750 GeV is due to two narrow scalars. We demonstrate that there is no n…
Transverse Parton Distribution Functions at Next-To-Next-To-Leading-Order
Thomas Gehrmann, Thomas Luebbert, Li Lin Yang
We present a perturbative calculation of the transverse parton distribution functions in all partonic channels up to next-to-next-to-leading order based on a gauge invariant operat…
Transverse parton distribution functions at next-to-next-to-leading order: the quark-to-quark case
Thomas Gehrmann, Thomas Lübbert, Li Lin Yang
We present a calculation of the perturbative quark-to-quark transverse parton distribution function at next-to-next-to-leading order based on a gauge invariant operator definition.…
Transverse-momentum resummation for top-quark pairs at hadron colliders
Hua Xing Zhu, Chong Sheng Li, Hai Tao Li +2
We develop a framework for a systematic resummation of the transverse momentum distribution of top-quark pairs produced at hadron colliders based on effective field theory. Compare…
Search for anomalous top quark production at the early LHC
Jun Gao, Chong Sheng Li, Li Lin Yang +1
We present a detailed study of the anomalous top quark production with subsequent decay at the LHC induced by model-independent flavor-changing neutral-current couplings, incorpora…
Two-loop divergences of scattering amplitudes with massive partons
Andrea Ferroglia, Matthias Neubert, Ben D. Pecjak +1
We complete the study of two-loop infrared singularities of scattering amplitudes with an arbitrary number of massive and massless partons in non-abelian gauge theories. To this en…
CP Asymmetry in from SUSY Flavor Changing Interactions
Xiao-Gang He, Chong-Sheng Li, Li-Lin Yang
Recently Babar and Belle collaborations have measured direct CP asymmetry in . The experimental value is substantially different from…
