Higgs triplet extension of GRACE
Much theoretical effort and automatization are required to confront new physics models with experimental data for many types of particle reactions at future colliders. In this context, we extend Grace, an automatic calculation system for invariant amplitudes, to incorporate particles and interactions in the Georgi–Machacek model. With the extended Grace system, we study fermiophobic Higgs boson production processes at $$e^+ e^-$$ and $$e^- e^-$$ colliders in the model. The results show some advantages of $$e^- e^-$$ colliders over $$e^+ e^-$$ colliders for new physics search and thus its complementary role.- 16 February 2022

We calculate the rapidity gap survival probability associated with the Higgs decay and Higgs plus dijet production in proton-proton collisions by resumming the leading non-global logarithms without any approximation to the number of colors. For dijet production, depending on partonic subprocesses, the probability involves various `color multipoles', i.e., the product of 4 ($qq\to qq$) or 6 ($qg\to qg$) or 8 ($gg\to gg$) Wilson lines. We calculate all these multipoles for a fixed dijet configuration and discuss the factorization of higher multipoles into lower multipoles as well as the validity of the large-$N_c$ approximation.

Further developments of FORM
Form is a symbolic manipulation system, which is especially advantageous for handling gigantic expressions with many small terms, as often occurs in real problems in perturbative quantum field theory. In this work we describe some main features of FORM, such as the preprocessor and $-variables with emphasizing on benefit of metaprogramming, and introduce a new feature: a topology generator.

Double Higgs boson production at colliders in the two-Higgs-doublet modelWe study the double Higgs boson production processes (), with being the 125 GeV Higgs boson in the two-Higgs-doublet model with a softly broken symmetry. The cross section can be significantly enhanced, typically a few hundred percent, as compared to the standard model prediction due to resonant effects of heavy neutral Higgs bosons, which becomes important in the case without the alignment limit. We find a strong correlation between the enhancement factor of the cross section and the scaling factor of the couplings under constraints from perturbative unitarity, vacuum stability, and current experimental data at the LHC as well as the electroweak precision data.- 22 May 2019
