One loop photon-graviton mixing in an electromagnetic field: Part 3

This paper utilizes the worldline formalism to present a unified one-loop calculation of photon-graviton mixing in an electromagnetic field, identifying a previously overlooked tadpole diagram that contributes to the amplitude but does not affect magnetic dichroism, while also extending the analysis to include scalar loops and electric field components.

Threshold resummation for ZZ-boson pair production at NNLO+NNLL

This paper presents the threshold resummation of large logarithms up to NNLL accuracy for on-shell ZZ-boson pair production at the LHC, demonstrating that matching these resummed predictions to NNLO fixed-order results significantly reduces scale uncertainties and provides a precise description of the invariant mass distribution in the high-energy regime.

The forward-backward asymmetry induced $CP$ asymmetry in B0Kπ+π0{\overline{B}}^{0}\rightarrow K^{-}π^{+}π^{0} in phase space around the resonances K(892)0{\overline{K}}^{*}(892)^{0} and K0(700){\overline{K}}^{*}_{0}(700)

This paper investigates the significant CP violation induced by forward-backward asymmetry in the decay B0Kπ+π0{\overline{B}}^{0}\rightarrow K^{-}\pi^{+}\pi^{0} within the phase space dominated by K(892)0\overline{K}^{*}(892)^{0} and K0(700){\overline{K}^{*}_{0}(700)} resonances, predicting asymmetries of up to 35% that are potentially observable by Belle and Belle-II collaborations.

Pseudoscalar Higgs boson decay to three parton amplitudes at NNLO to higher orders in the dimensional regulator

This paper presents the first calculation of second-order corrections for pseudo-scalar Higgs boson decay into three partons (AgggA \to ggg and AqqˉgA \to q\bar{q}g) expanded to higher orders in the dimensional regulator within an effective theory framework, providing finite amplitude pieces essential for predicting NNLO differential distributions and future three-loop cross sections at hadron colliders.
