Probing the W tb vertex structure in t-channel single-top-quark production and decay in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
To probe the W tb vertex structure, top-quark and W -boson polarisation observables are measured from t-channel single-top-quark events produced in proton-proton collisions at a centre-of-mass energy of 8 TeV.

Single spin asymmetries in inclusive high energy hadron-hadron collision processes [PDF]

open access: yes, 2000
It has been realized for quite a long time that single-spin experiments, in which one of the colliding objects is transversely polarized, can be helpful in studying the properties of strong interaction in general and in testing Quantum Chromodynamics ...

Primordial nucleosynthesis and hadronic decay of a massive particle with a relatively short lifetime [PDF]

open access: yes, 2001
In this paper we consider the effects on big bang nucleosynthesis (BBN) of the hadronic decay of a long-lived massive particle. If high-energy hadrons are emitted near the BBN epoch ($t \sim 10^{-2}$ -- $10^2 \sec$), they extraordinarily inter-convert ...

Studies of J/ψ production at forward rapidity in Pb–Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2020
The inclusive J/ψ production in Pb–Pb collisions at the center-of-mass energy per nucleon pair s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV, measured with the ALICE detector at the CERN LHC, is reported.

Transforming the bootstrap: using transformers to compute scattering amplitudes in planar N=4 super Yang–Mills theory [PDF]

open access: yesMachine Learning: Science and Technology
We pursue the use of deep learning methods to improve state-of-the-art computations in theoretical high-energy physics. Planar N=4 Super Yang–Mills theory is a close cousin to the theory that describes Higgs boson production at the Large Hadron Collider;

The emergence of multi-lepton anomalies at the LHC and their compatibility with new physics at the EW scale

open access: yesJournal of High Energy Physics, 2019
A recent study [1] has shown that a simplified model predicting a heavy scalar of mass 270 GeV (H ) that decays to a Standard Model (SM) Higgs boson in association with a scalar singlet of mass 150 GeV (S) can accommodate several anomalous multi-lepton ...

Study of the rare decays of B s 0 and B 0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A study of the decays B s 0 → μ + μ − and B 0 → μ + μ − has been performed using 26.3 fb−1 of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016.

Matrix element regression with deep neural networks — Breaking the CPU barrier

open access: yesJournal of High Energy Physics, 2021
The Matrix Element Method (MEM) is a powerful method to extract information from measured events at collider experiments. Compared to multivariate techniques built on large sets of experimental data, the MEM does not rely on an examples-based learning ...

High energy inelastic electron hadron scattering, in peripheral kinematics. Sum rules for hadron form factors [PDF]

open access: yes, 2006
Relations between differential cross section for inelastic scattering of electrons on hadrons and hadron form factors (sum rules) are derived on the basis of analytical properties of heavy photon forward Compton scattering on hadrons.

Diffraction at HERA and the Confinement Problem [PDF]

open access: yes, 2000
We discuss HERA data on the high energy behavior of the total gamma*p cross section and on diffraction in deep inelastic scattering. We outline their novelty in comparison with diffraction in high energy hadron hadron scattering.
