Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

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 …

The imbalance of matter and antimatter in our Universe provides compelling motivation to
search for undiscovered particles that violate charge-parity symmetry. Interactions with …

A bstract The future high-energy muon colliders, featuring both high energy and low
background, could play a critical role in our searches for new physics. The smallness of …

This report, as part of the 2021 Snowmass Process, summarizes the current status of collider
physics at the Energy Frontier, the broad and exciting future prospects identified for the …

The Top Yukawa coupling profoundly influences several core mysteries linked to the
electroweak scale and the Higgs boson. We study the feasibility of measuring the Top …

Analyses of astrophysical data provide first hints on the self-interactions of dark matter at low
energies. Lattice calculations of dark matter theories can be used to investigate them …

A bstract With the help of Young tensor technique, we enumerate the complete and
independent set of effective operators up to dim-8 for the extension of the standard model …

A bstract The standard model can be extended to include weakly-interacting light particle
(WILP): real or complex singlet scalar with a conserved U (1) charge, Majorana or Dirac …

In this review, we discuss and extend the study of the inclusive production of vector
quarkonia, J/ψ and Υ, emitted with large transverse momenta and rapidities at the LHC. We …
