This report presents a comprehensive collection of searches for new physics performed by
the ATLAS Collaboration during the Run 2 period of data taking at the Large Hadron …

We review the theory and phenomenology of isosinglet vector-like quarks (VLQs). In recent
years, interest in VLQs has been increasing, due to their contributions to new physics effects …

We have searched for proton decay via p→ e+ π 0 and p→ μ+ π 0 modes with the enlarged
fiducial volume data of Super-Kamiokande from April 1996 to May 2018, which corresponds …

A bstract Non-invertible global symmetry often predicts degeneracy in axion potentials and
carries important information about the global form of the gauge group. When these …

The standard model of hot big-bang cosmology requires initial conditions which are
problematic in two ways:(1) The early universe is assumed to be highly homogeneous, in …

A number of properties of possible baryon-and lepton-nonconserving processes are shown
to follow under very general assumptions. Attention is drawn to the importance of measuring …

We study candidate vacuum configurations in ten-dimensional O (32) and E 8× E 8
supergravity and superstring theory that have unbroken N= 1 supersymmetry in four …

We review physics of light pseudoscalars (axions, majorons and familons) and their effects
in cosmology. The axions which solve the strong CP problem play important roles in …

In this report we survey the low-energy phenomenological implications of superstring-
inspired E 6 models. The motivation for such models is reviewed. New particles including …

The results gathered here on simple Lie algebras have been selected with attention to the
needs of unified model builders who study Yang-Mills theories based on simple, local …
