We consider the scalar sector of a general renormalizable theory and evaluate the effective potential through three loops analytically. We encounter three-loop vacuum bubble diagrams with up to two masses and six lines, which we solve using differential equations transformed into the favorable ϵ form of dimensional regularization.

Prospects for Higgs boson differential cross section measurements for the full expected High-Luminosity LHC (HL-LHC) luminosity of 3 ab$^{−1}$ are performed using the$H → γγ, H → Z Z^v∗ → 4 \ell$ decay channels, as well as their combination. Differential cross section measurements are presented for the Higgs boson transverse momentum, Higgs boson rapidity, number of jets produced together with the Higgs boson, and the transverse momentum of the leading jet..

This note reports measurements of Higgs boson properties in the two-photon final state using 79.8 fb$^{-1}$ of data recorded at $\sqrt{s}=13$ TeV by the ATLAS experiment at the Large Hadron Collider. The cross sections of Higgs boson production through gluon--gluon fusion, vector-boson fusion, and in association with a vector boson or a top-quark pair are measured. [...]

Properties of the Higgs boson are measured in the two-photon final state using 36 fb$^{-1}$ of proton--protoncollision data recorded at $\sqrt{s} = 13$ TeV by the ATLAS experiment at the Large Hadron Collider. Cross-section measurements for the production of a Higgs boson through gluon--gluon fusion, vector-boson fusion, and in association with a vector bosonor a top-quark pair are reported. [...]

We compute dual-conformally invariant ladder integrals that are capped off by pentagons at each end of the ladder. Such integrals appear in six-point amplitudes in planar $\mathcal{N}=4$ super-Yang-Mills theory. [...]

Motivated by the persisting ''anomaly'' in the measurement of $P′_5$, we review hadronic uncertainties entering the angular observables of the decay$\bar{B}\to \bar{K}^*\mu^+\mu^-$. We argue that hadronic uncertainties could account for the present measurements [...]

Dwarf spheroidal galaxies are among the most promising targets for detecting signals of Dark Matter (DM) annihilations. The H.E.S.S. [...]

We present a formalism to resum large threshold logarithms to all orders in perturbative QCD for the rapidity distribution of any colorless particle at the hadron colliders. Using the derived resummed coefficients in two dimensional Mellin space, we present the rapidity distributions for the Higgs as well as for the Drell-Yan production to NNLO+NNLL accuracy at the LHC.
