Probing Standard Model-like di-Higgs Production at Photon-Photon Colliders in the I(1+2)HDM Type-I

Abdesslam Arhrib, Ayoub Hmissou, Stefano Moretti, Larbi Rahili

In this paper, pair production of Standard Model (SM)-like Higgs bosons, $hh$, is studied through $γγ$ scattering at future electron-positron colliders, in the framework of the Inert Doublet Model with two Active Doublets, i.e., the I(1+2)HDM for short. The relevance of the process $γγ\to hh$ for…

Stellar-like Galactic center excess challenges particle dark matter

Silvia Manconi, Christopher Eckner, Francesca Calore, Fiorenza Donato

The Galactic Center (GC) is potentially hosting the largest indirect signal from particle dark matter (DM), which in many well-motivated models would produce gamma rays as their final states. However, this region has often been dismissed for DM studies because of the evidence for an unexpected…

Statistical Indications of Toponium Formation in Top Quark Pair Production

Benjamin Fuks, Aminul Hossain, James Keaveney

We present an analysis of six differential cross-section measurements of top-quark pair production in the dilepton channel from the ATLAS and CMS experiments. The data are compared to state-of-the-art QCD predictions with and without the inclusion of toponium formation effects. This contribution is…

Revisiting the Quantum Geometry of Torus-fibered Calabi-Yau Threefolds

Boris Pioline, Thorsten Schimannek

About ten years ago, Katz, Klemm and Huang conjectured that topological string amplitudes on compact, elliptically fibered Calabi-Yau threefolds at fixed base degree could be expressed in terms of meromorphic Jacobi forms for $SL(2,\mathbb{Z})$, giving access to Gromov-Witten invariants at…
