AI Article Synopsis
- The study calculates next-to-next-to-leading order QCD corrections for Higgs boson pair production at hadron colliders, focusing on the large top-mass approximation.
- At the LHC, these corrections increase the inclusive cross section by about 20% compared to the next-to-leading order results at a center-of-mass energy of 14 TeV.
- The findings show a significant reduction in scale dependence, and the paper includes analytical expressions for the K factors based on the center-of-mass energy.
Article Abstract
We compute the next-to-next-to-leading order QCD corrections for standard model Higgs boson pair production inclusive cross section at hadron colliders within the large top-mass approximation. We provide numerical results for the LHC, finding that the corrections are large, resulting in an increase of O(20%) with respect to the next-to-leading order result at c.m. energy sqrt[sH]=14 TeV. We observe a substantial reduction in the scale dependence, with overlap between the current and previous order prediction. All our results are normalized using the full top- and bottom-mass dependence at leading order. We also provide analytical expressions for the K factors as a function of sH.

We report a combined electrical transport and optical study of the superconductivity in atomically thin NbSe_{2}. When subjected to an out-of-plane magnetic field, an anomalous metallic state emerges, characterized by a finite longitudinal resistance and a vanishing Hall resistance, suggesting the presence of particle-hole symmetry. We establish a superconducting Higgs mode in atomically thin samples, which reveals enduring superconducting fluctuations that withstand unexpectedly high reduced magnetic fields.

We extend the Quantum Memory Matrix (QMM) framework, originally developed to reconcile quantum mechanics and general relativity by treating space-time as a dynamic information reservoir, to incorporate the full suite of Standard Model gauge interactions. In this discretized, Planck-scale formulation, each space-time cell possesses a finite-dimensional Hilbert space that acts as a local memory, or , for matter and gauge field configurations. We focus on embedding non-Abelian SU(3) (quantum chromodynamics) and SU(2) × U(1) (electroweak interactions) into QMM by constructing gauge-invariant imprint operators for quarks, gluons, electroweak bosons, and the Higgs mechanism.

We apply the recently developed concept of the nucleon energy-energy correlator (NEEC) for the gluon sector to investigate the long-range azimuthal angular correlations in proton-proton collisions at the Large Hadron Collider. The spinning gluon in these collisions will introduce substantial nonzero asymmetries in both Higgs boson and top quark pair productions, where is the azimuthal angle between the forward and backward energy correlators in the NEEC observables. The genesis of the correlation lies in the intricate quantum entanglement.

A search for light long-lived particles (LLPs) decaying to displaced jets is presented, using a data sample of proton-proton collisions at a center-of-mass energy of 13.6 TeV, corresponding to an integrated luminosity of 34.7 fb, collected with the CMS detector at the CERN LHC in 2022.

Understanding how symmetry-breaking processes generate order out of disorder is among the most fundamental problems of nature. The scalar Higgs mode - a massive (quasi-) particle - is a key ingredient in these processes and emerges with the spontaneous breaking of a continuous symmetry. Its related exotic and elusive axial counterpart, a Boson with vector character, can be stabilized through the simultaneous breaking of multiple continuous symmetries.
