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 …

A bstract We consider Zγ production in hadronic collisions and present the first computation
of next-to-next-to-leading order accurate predictions consistently matched to parton showers …

The production of a prompt photon in association with a $ Z $ boson is studied in proton-
proton collisions at a centre-of-mass energy $\sqrt {s}= $13 TeV. The analysis uses a data …

A bstract We study the anomalous ZZγ and Zγγ couplings that can be probed via Zγ
production at the e+ e− colliders. We take Standard Model Effective Field Theory (SMEFT) …

A bstract Using the functional method, one-loop matching of the type-I,-II and-III see-saw
models are investigated and the results are presented in both the Green's and the Warsaw …

A bstract We investigate the measurement of non-standard ZZV (V= γ, Z) couplings through
Z-boson pair production at the e+ e− colliders. We adopt the Standard Model Effective Field …

The precise measurement of physics observables and the test of their consistency within the
standard model (SM) are an invaluable approach, complemented by direct searches for new …

The electroweak production of $ Z (\nu\bar {\nu})\gamma $ in association with two jets is
studied in a regime with a photon of high transverse momentum above 150 GeV using …

A bstract Higgs sectors extended by electroweakly charged scalars can be explored by
scalar pair production at the LHC. We consider a fermiophobic scenario, with decays into a …

Composite Higgs models usually contain additional pseudo Nambu Goldstone bosons and
vector-like quarks. We discuss various aspects related to their LHC phenomenology and …
