Theoretical particle physics articles from across Nature Portfolio

Theoretical particle physics is the development of models for describing fundamental particles and their interactions. This includes testing and refining the prevailing theory: the standard model. Theoretical particle physics can also include developing the computation tools required to analyse vast quantities of data produced from particle-collider experiments.

    Observations of the Schwinger effect—the creation of matter by electric fields—have been hindered by the high required field strength. A mesoscopic variant of the Schwinger effect has now been realized in graphene transistors.

    The tension between measured W mass and its Standard Model prediction might arise from uncertainties in the hadronic contribution, and the same is true for the muon g − 2. Here, the authors show that such a common origin for the two anomalies is unlikely, while a model involving leptoquarks might explain them both.

    The behaviour of quantum fields in curved spacetime is simulated using a two-dimensional trapped quantum gas of potassium atoms with a configurable trap and adjustable interaction strength.

    Holographic duality, which relates systems with and without gravity, suggests that quantum entanglement is essential for understanding gravitational phenomena on a fundamental level. The authors conjecture an infinite set of necessary conditions for a quantum state, which can holographically describe a semiclassical gravitational spacetime, and relate those conditions to properties of evaporating black holes.

    Precisely calculating differences between muon- and electron-neutrino interactions is difficult, but is vital for correctly interpreting neutrino oscillation experiments. Here, the authors determine the effect of electromagnetic quantum corrections in the predicted ratio of ve and vμ cross sections.

    As we celebrate the ten-year anniversary of the discovery of the Higgs boson, CERN’s Director-General at that time reminisces about the years leading up to this milestone.

    In 2021, the most precise measurement of the muon’s anomalous magnetic moment and a new high-precision lattice quantum chromodynamics calculation have in turn kindled, then dimmed, hopes for seeing signs of new physics. State-of-the-art calculations, made possible by a series of recent advances, will be key to understanding these conflicting results.
