11. ALP-ine quests at the LHC: hunting axion-like particles via peaks and dips in top-antitop-quark production
Laurids Jeppe (Deutsches Elektronen-Synchrotron (DE))
Poster

We present an analysis of the sensitivity of LHC searches for a new spin-0 particle decaying into top-antitop-quark ($t\bar{t}$) final states to generic axion-like particles (ALPs) coupled to top quarks and gluons. As a first step, we derive new limits on the effective ALP Lagrangian in terms of the respective Wilson coefficients based on the results of a CMS search using 35.9...
75. Application of Machine Learning Top and W Jet Tagging to Hadronic Four-Top Final States
Petr Baron (Palacky University (CZ))
Poster

We present an application of the gradient boosting machine learning technique for tagging top quark and W jets in hadronic four-top final states induced by both Standard Model (SM) and Beyond the Standard Model (BSM) processes. Our approach utilizes classical subjettiness variables within the framework of the Delphes common parameterized detector simulation package. Jets produced in simulated...
8. Complete NLO corrections to off-shell ttZ production at the LHC
Daniele Lombardi (Universität Würzburg)
YSF talk

The comparison of theory predictions and experimental measurements is one of the main roads for discovering physics beyond the Standard Model. The tremendous amount of data that has been and will be further collected at the LHC already demands a high level of precision from the theory predictions.
In this talk I will focus on ttZ production, whose phenomenological interest is...
73. CP-sensitive simplified template cross-sections for $t\bar t H$
Alberto Carnelli (Université Paris-Saclay (FR))
Poster

The CP structure of the Higgs boson is a fundamental property which has not yet been constrained with high precision. CP violation in the Yukawa coupling between the Higgs boson and top quark pair can be probed directly at the Large Hadron Collider by measuring top-quark-associated Higgs production. Multivariate analysis techniques commonly developed so far by the experiments are designed for...
4. Encoding off-shell effects in top pair production in direct diffusion networks
Mathias Kuschick
YSF talk

Promoting predictions for top quark production to include off-shell effects comes at an exceptionally high computational cost. On an example of $l^+\nu l^-\bar{nu} b \bar{b}$ process, dominated by top quark pair production and decay in the dilepton channel, we show how to reliably encode off-shell effects in a generative neural network based on direct diffusion. This network, constructed using...

Van Dung Le
Poster

We will report on an extensive survey of rare and exclusive few-body decays of the top quark, defined as those with branching fractions BR≲$10^{-5}$ and two or three final particles [[1]]. Such rare decays probe physics beyond the Standard Model (BSM), constitute a background for exotic decays into new BSM particles, and provide precise information on quantum chromodynamics factorization with...

YSF talk

In this talk, I will discuss the status of the calculation of the two-loop QCD corrections to the production of a top-quark pair associated with a jet at hadron colliders. This is the main bottleneck for achieving NNLO predictions. I will review recent progress in calculating the required Feynman integrals using the method of differential equations. I will also present the cutting-edge...
