Three-loop large-$N_c$ virtual corrections to $gg\to HH$ in the forward limit
abstract
We compute the three-loop form factors for $gg\to HH$ in the limit of vanishing transverse momentum of the Higgs boson which provides a reasonable approximation of the cross section. In our calculations we adopt the large-$N_c$ limit, which already includes non-trivial non-planar Feynman diagrams. We discuss the results for top quark masses in the pole and $\overline{\rm MS}$ schemes and show that the scheme dependence is significantly reduced at next-to-next-to-leading order.

Electroweak corrections to Higgs boson pair production: The quark channel
Mixed QCD-EW corrections to qqbar -> HH computed analytically via differential equations, matched to large-mass limit, implemented in POWHEG-BOX, showing up to +10% effect on invariant mass distribution near threshold.

Fully differential Higgs boson pair production at N$^3$LO with top quark mass effects
First fully differential N3LO QCD predictions for gg->hh in the heavy-top limit, with NLO top-mass effects added; heavy-top scale uncertainty shrinks about 3x, to roughly 1-3%.

$B$-meson decay width up to $1/m_b^3$ corrections within and beyond the Standard Model
Complete analytic HQE matching coefficients for B-meson decay widths up to 1/m_b^3 are derived for generic new-physics operators, including previously missing weak-annihilation terms.

Higgs-Pair Production via Gluon Fusion: Top-Yukawa- and light-quark-induced electroweak Corrections
The top-Yukawa and light-quark electroweak corrections to Higgs-pair production at the LHC shift the total cross section by about −3.4%, with differential corrections of 5–10% at high invariant mass.
