Theory versus experiments in heavy flavour production [PDF]

, 2001
I discuss the current status of the comparison between theoretical predictions and experimental data, relevant to the production of open charm and bottom quarks in photon-hadron and photon-photon collisions. I advocate the use of a formalism that matches

Two-loop amplitudes for Higgs plus jet production involving a modified trilinear Higgs coupling

Journal of High Energy Physics, 2019
We calculate the contributions to the two-loop scattering amplitudes h → gg, h → ggg and h → q q ¯ g $$ h\to q\overline{q}g $$ that arise from a modified trilinear Higgs coupling λ.

Two-loop QCD-EW master integrals for Z plus jet production at large transverse momentum

Journal of High Energy Physics, 2020
The production of electroweak Z bosons that decay to neutrinos and recoil against jets with large transverse momentum p ⊥ is an important background process to searches for dark matter at the Large Hadron Collider (LHC).

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

Advanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

High multiplicity processes at NLO with BlackHat and Sherpa

, 2012
In this contribution we review recent progress with fixed-order QCD predictions for the production of a vector boson in association with jets at hadron colliders, using the programs BlackHat and SHERPA. We review general features of next-to-leading-order

Heavy-quark mass effects in Higgs boson production at the LHC [PDF]

, 2013
We study the impact of heavy-quark masses in Higgs boson production through gluon fusion at the LHC. We extend previous computations of the fully differential cross section and of the transverse momentum spectrum of the Higgs boson by taking into account

Interpretable Machine Learning for Bandgap Prediction and Descriptor‐Guided Design Rules of Phosphates

Advanced Intelligent Discovery, EarlyView.
An explainable CatBoost model was trained to predict the bandgaps of 474 phosphate crystals based on composition and density descriptors. SHAP analysis identified two key variables—d‐electron‐count dispersion and atomic‐density dispersion—as the primary drivers of the model's predictions.

Determination of the top quark mass from leptonic observables [PDF]

, 2014
We present a procedure for the determination of the mass of the top quark at the LHC based on leptonic observables in dilepton $t\bar{t}$ events. Our approach utilises the shapes of kinematic distributions through their few lowest Mellin moments; it is ...

Top-Yukawa contributions to bbH production at the LHC

Journal of High Energy Physics, 2019
We study the production of a Higgs boson in association with bottom quarks b b ¯ H $$ \left(b\overline{b}H\right) $$ in hadronic collisions at the LHC, including the different contributions stemming from terms proportional to the top-quark Yukawa ...
