In this note, we give a definitive basis for the dimension-eight operators leading to quartic - but no cubic - interactions among electroweak gauge bosons. These are often called anomalous quartic gauge couplings, or aQGCs. [...]

Theoretical investigations into the evolution of the early universe are an essential part of particle physics that allow us to identify viable extensions to the Standard Model as well as motivated parameter space that can be probed by various experiments and observations. [...]

CEPC Technical Design Report: Accelerator
/ CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar). [...]

Probing the Scale of New Physics in the $ZZ\gamma$ Coupling at $e^+e^-$ Colliders

The $ZZ\gamma$ triple neutral gauge couplings are absent in the Standard Model (SM) at the tree level. They receive no contributions from dimension-6 effective operators, but can arise from effective operators of dimension-8. [...]

Pulsar Timing Probes of Primordial Black Holes and Subhalos
/ Dror, Jeff A. (LBL, Berkeley ; UC, Berkeley) ; Ramani, Harikrishnan (LBL, Berkeley ; UC, Berkeley) ; Trickle, Tanner (LBL, Berkeley ; UC, Berkeley) ; Zurek, Kathryn M. (CERN ; LBL, Berkeley ; UC, Berkeley)
Pulsars act as accurate clocks, sensitive to gravitational redshift and acceleration induced by transiting clumps of matter. We study the sensitivity of pulsar timing arrays (PTAs) to single transiting compact objects, focusing on primordial black holes and compact subhalos in the mass range from $10^{-12} M _{\odot}$ to well above $100~M_\odot$. [...]

Cosmology at high redshift — a probe of fundamental physics
/ Sailer, Noah (UC, Berkeley) ; Castorina, Emanuele (Milan U. ; CERN) ; Ferraro, Simone (LBNL, Berkeley ; UC, Berkeley (main)) ; White, Martin (UC, Berkeley ; LBNL, Berkeley)
An observational program focused on the high redshift ($2<z<6$) Universe has the opportunity to dramatically improve over upcoming LSS and CMB surveys on measurements of both the standard cosmological model and its extensions. Using a Fisher matrix formalism that builds upon recent advances in Lagrangian perturbation theory, we forecast constraints for future spectroscopic and 21-cm surveys on the standard cosmological model, curvature, neutrino mass, relativistic species, primordial features, primordial non-Gaussianity, dynamical dark energy, and gravitational slip. [...]

A Heavy QCD Axion and the Mirror World
/ Dunsky, David I. (New York U., CCPP ; UC, Berkeley ; LBL, Berkeley) ; Hall, Lawrence J. (UC, Berkeley ; LBL, Berkeley) ; Harigaya, Keisuke (Chicago U. ; Chicago U., EFI ; Chicago U., KICP ; Tokyo U., IPMU ; CERN)
We study the mirror world with dark matter arising from the thermal freeze-out of the lightest, stable mirror particle -- the mirror electron. The dark matter abundance is achieved for mirror electrons of mass 225 GeV, fixing the mirror electroweak scale near $10^8$ GeV. [...]
