Quantum Tomography of Top Quarks as a Probe of Charge-Parity Violation
Eren Erdogan, Kirtimaan A. Mohan, Keping Xie +1
LHC measurements now reconstruct all fifteen parameters of the two-qubit spin density matrix, which amounts to a full quantum tomography of the pair. We show that this da…
Global fits and the 95 GeV diphoton excesses in the Supersymmetric Georgi-Machacek Model
Yingnan Xu, Dikai Li, Roberto Vega +2
Recently the ATLAS and CMS experiments have reported modest excesses in the diphoton channel at around 95 GeV.~A number of recent studies have examined whether these could be due t…
CT25: Progress toward next-generation PDFs for precision phenomenology at the LHC
A. Ablat, A. Courtoy, S. Dulat +10
We summarize recent progress toward the next generation of CTEQ-TEA parton distribution functions, CT25, based on a global NNLO analysis that incorporates a significant sample of n…
QED-enhanced PDF implications for the Higgs sector
Amanda M. Cooper-Sarkar, Thomas Cridge, T. J. Hobbs +4
In this work, we examine the implications of electroweak corrections beyond leading order for processes of special interest in the Higgs sector. We especially explore the role of t…
Impact of lattice gluon dataset on CTEQ-TEA global PDFs
Alim Ablat, Sayipjamal Dulat, Tie-Jiun Hou +3
We investigate the impact of the latest gluon parton results from lattice QCD on the global parton distribution function (PDF) analysis within the CTEQ-TEA framework. The dependenc…
General mass variable flavor number scheme for boson production in association with a heavy quark at hadron colliders
Marco Guzzi, Pavel Nadolsky, Laura Reina +2
We present a methodology to streamline implementation of massive-quark radiative contributions in calculations with a variable number of active partons in proton-proton collisions.…
