Physics beyond colliders at CERN: beyond the Standard Model working group report [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2019
The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting the full scientific potential of the CERN's accelerator complex and scientific infrastructures through projects complementary to the LHC and other possible future ...

Comprehensive analysis of beta decays within and beyond the Standard Model [PDF]

open access: yesJournal of High Energy Physics, 2020
Precision measurements in allowed nuclear beta decays and neutron decay are reviewed and analyzed both within the Standard Model and looking for new physics. The analysis incorporates the most recent experimental and theoretical developments. The results

Closing the window for compressed dark sectors with disappearing charged tracks

open access: yesJournal of High Energy Physics, 2017
We investigate the sensitivity at current and future hadron colliders to a heavy electrically-charged particle with a proper decay length below a centimetre, whose decay products are invisible due to below-threshold energies and/or small couplings to the

Lattice tests of beyond standard model dynamics [PDF]

open access: yes, 2015
Over the last few years lattice techniques have been used to investigate candidate theories of new physics beyond the Standard Model. This review gives a survey of results from these studies.

New physics explanations of a μ in light of the FNAL muon g − 2 measurement

open access: yesJournal of High Energy Physics, 2021
The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment a μ FNAL $$ {a}_{\mu}^{\mathrm{FNAL}} $$ , which is in full agreement with the previous BNL measurement and pushes the world average deviation ∆ a ...

Vacuum stability in the Standard Model and beyond [PDF]

open access: yesPhysical Review D
We revisit the stability of the Standard Model vacuum and investigate its quantum effective potential using the highest available orders in perturbation theory and the most accurate determination of input parameters to date. We observe that the stability

The Standard Model and Beyond [PDF]

open access: yesAIP Conference Proceedings, 1986
This new edition of The Standard Model and Beyond presents an advanced introduction to the physics and formalism of the standard model and other non-abelian gauge theories. It provides a solid background for understanding supersymmetry, string theory, extra dimensions, dynamical symmetry breaking, and cosmology.

How heavy can neutralino dark matter be?

open access: yesJournal of High Energy Physics, 2019
What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are extremely degenerated in mass, with a mass difference less than the QCD ...

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2019
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay ...
