Electroweak splitting functions and high energy showering

Journal of High Energy Physics, 2017
We derive the electroweak (EW) collinear splitting functions for the Standard Model, including the massive fermions, gauge bosons and the Higgs boson. We first present the splitting functions in the limit of unbroken SU(2) L × U(1) Y and discuss their ...

Heavy neutral leptons at the Electron-Ion Collider

Journal of High Energy Physics, 2023
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory, along with its primary capacity to elucidate the nuclear structure, will offer new opportunities to probe physics beyond the Standard Model coupled to the electroweak sector. Among

Extragalactic and cosmological tests of gravity theories with additional scalar or vector fields [PDF]

, 2011
Despite the many successes of the current standard model of cosmology on the largest physical scales, it relies on two phenomenologically motivated constituents, cold dark matter and dark energy, which account for approximately 95% of the energy-matter ...

Structure of Chern-Simons scattering amplitudes from topological equivalence theorem and double-copy

Journal of High Energy Physics, 2022
We study the mechanism of topological mass-generation for 3d Chern-Simons (CS) gauge theories, where the CS term can retain the gauge symmetry and make gauge boson topologically massive.

Massive color-kinematics duality and double-copy for Kaluza-Klein scattering amplitudes

Journal of High Energy Physics, 2023
We study the structure of scattering amplitudes of massive Kaluza-Klein (KK) states under toroidal compactification. We present a shifting method to quantitatively derive the scattering amplitudes of massive KK gauge bosons and KK gravitons from the ...

Heavy quark jet fragmentation

Journal of High Energy Physics, 2018
In this paper we study the fragmentation of a parton into a jet containing a heavy quark. When heavy quarks are involved in a jet, the quark mass can lead to a numerically significant correction to the jet cross section and its substructure.

Breaking mirror twin color

Journal of High Energy Physics, 2020
We investigate simple extensions of the Mirror Twin Higgs model in which the twin color gauge symmetry and the discrete ℤ2 mirror symmetry are spontaneously broken. This is accomplished in a minimal way by introducing a single new colored triplet, sextet,

Keeping it simple: simplified frameworks for long-lived particles at neutrino facilities

Journal of High Energy Physics, 2023
Modern-day accelerator neutrino facilities are excellent venues for searches for new-physics particles. Many distinct new-physics models predict overlapping signatures and phenomenology in these experiments.

Hybrid renormalization for quasi distribution amplitudes of a light baryon

Journal of High Energy Physics, 2023
We develop a hybrid scheme to renormalize quasi distribution amplitudes of a light baryon on the lattice, which combines the self-renormalization and ratio scheme.
