Global analysis of electroweak data in the Standard Model

J. de Blas, M. Ciuchini, E. Franco +5

We perform a global fit of electroweak data within the Standard Model, using state-of-the art experimental and theoretical results, including a determination of the electromagnetic…

Hadroproduction of four top quarks in the POWHEG BOX

Tomáš Ježo, Manfred Kraus

We present a new Monte Carlo event generator for the hadronic production of four top quarks in the POWHEG BOX framework. Besides the dominant next-to-leading order QCD corrections…

Deep Learning Exotic Hadrons

JPAC Collaboration, L. Ng, L. Bibrzycki +6

We perform the first model independent analysis of experimental data using Deep Neural Networks to determine the nature of an exotic hadron. Specifically, we study the line shape o…

Leading-Color Two-Loop Amplitudes for Four Partons and a W Boson in QCD

S. Abreu, F. Febres Cordero, H. Ita +3

We present the leading-color two-loop QCD corrections for the scattering of four partons and a boson, including its leptonic decay. The amplitudes are assembled from the planar…

Publishing statistical models: Getting the most out of particle physics experiments

Kyle Cranmer, Sabine Kraml, Harrison B. Prosper +30

The statistical models used to derive the results of experimental analyses are of incredible scientific value and are essential information for analysis preservation and reuse. In…

CJ15 global PDF analysis with new electroweak data from the STAR and SeaQuest experiments

Sanghwa Park, Alberto Accardi, Xiaoxian Jing +1

We present updates to a recent CTEQ-Jefferson Lab (CJ) global analysis of parton distribution functions with a new set of electroweak data that provide unique access to quark flavo…

Heavy QCD Axion at Belle II: Displaced and Prompt Signals

Emilie Bertholet, Sabyasachi Chakraborty, Vazha Loladze +3

The QCD axion is a well-motivated addition to the standard model to solve the strong problem. If the axion acquires mass dominantly from a hidden sector, it can be as heavy…

Composite neutrinos and the QCD axion: baryogenesis, dark matter, small Dirac neutrino masses, and vanishing neutron EDM

Sabyasachi Chakraborty, Tae Hyun Jung, Takemichi Okui

We consider a chiral gauge theory from which light composite Dirac neutrinos dynamically emerge, augmented by a QCD axion to solve the strong CP problem. We show that an interplay…

at the LHC: On the size of corrections and -jet definitions

Giuseppe Bevilacqua, Huan-Yu Bi, Heribertus Bayu Hartanto +3

We report on the calculation of the next-to-leading order QCD corrections to the production of a pair in association with two heavy-flavour jets. We concentrate on the d…

Leading-Color Two-Loop QCD Corrections for Three-Jet Production at Hadron Colliders

S. Abreu, F. Febres Cordero, H. Ita +2

We present the complete set of leading-color two-loop contributions required to obtain next-to-next-to-leading-order (NNLO) QCD corrections to three-jet production at hadron collid…

Feebly-Interacting Particles:FIPs 2020 Workshop Report

Prateek Agrawal, Martin Bauer, James Beacham +43

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader part…

Heavy QCD Axion in transition: Enhanced Limits and Projections

Sabyasachi Chakraborty, Manfred Kraus, Vazha Loladze +2

We study a "heavy" QCD axion whose coupling to the standard model is dominated by but with . This is well motivated as it can solve the str…

Updates to the One-loop Provider NLOX

Diogenes Figueroa, Seth Quackenbush, Laura Reina +1

We describe the 1.2 update to NLOX, a computer program for calculations in high-energy particle physics. New features since the 1.0 release and other changes are described, along w…

Top-quark pair production in association with a gauge boson in the POWHEG-BOX

F. Febres Cordero, M. Kraus, L. Reina

We present a new Monte Carlo event generator for the production of a top-quark pair in association with a boson at hadron colliders in the POWHEG-BOX framework. We consider…
