タイトル： Higgs Production Classifier using Weak Supervision

概要：A reliable determination of the Higgs production mechanism in hadron collider experiments is essential in the program of the measurements of the Higgs couplings.
We employ weak supervision, CWoLa in particular, to train deep neural networks using real data of the diphoton events,
in the hope of reducing biases resulting from Monte Carlo simulations. Models based on the convolutional neural network and the transformer are tested and compared.
In particular, the classification performance gets slightly better when the photon information is removed from training.
We explicitly show that the performance can be improved when the training dataset is enlarged by data augmentation using physics-motivated methods.
We further demonstrate that the trained model can be successfully applied to the h \to ZZ and Z \gamma events,
showing that such classifiers are agnostic to Higgs decay modes provided they do not involve strong QCD corrections.

概要：本講演では，右巻きニュートリノと次元6の電磁双極子演算子を用いた(共鳴)電磁レプトジェネシスの解析を，
有効場理論に基づいて行う．
Part IではUV完備模型から電磁双極子演算子と付随するWilson係数を1-loopマッチングし，RGEにより電弱スケールにおけるBAU生成への強い抑制を定量化する．
Part IIでは準縮退した右巻きニュートリノの自己エネルギーを再和し，それに伴う共鳴が電弱スケールのBAUを観測値まで増幅し得ることを示す．
Part IIIではWeinberg演算子と荷電レプトン双極子演算子を評価し，軽いニュートリノ質量，μ→eγ，電子EDM，(g-2)_μとの整合性を調べ

タイトル： A roadmap to CP-violation searches at the Large Hadron Collider
講演者：Prof. Rui Santos（Lisbon University）
日時：１月１９日（月）１４：４０-
場所：１号館１３４教室
概要：Understanding the origin of CP-violation remains one of the central open questions in particle physics, with profound implications for the matter–antimatter asymmetry of the Universe. The Large Hadron Collider (LHC), with its unprecedented energy and luminosity, offers multiple complementary avenues to probe CP-violating phenomena within and beyond the Standard Model. In this talk, I will present a structured roadmap for current and future CP-violation searches at the LHC. Emphasis will be placed on the interplay between theory and experiment. This roadmap aims to provide both a synthesis of the current landscape and a guide for maximising discovery potential in the coming decade.
