New sum rules for the B$_{c}$→ J/ψ form factors / Bordone, Marzia (CERN) ; Khodjamirian, Alexander (Siegen U.) ; Mannel, Th. (Siegen U.)
We derive new sum rules for the form factors of the $B_c\to J/\psi\, \ell \bar{\nu}_\ell$ semileptonic transitions, employing the vacuum-to-$B_c$ correlation function of the $J/\psi$-interpolating and $b\to c$ weak currents. In the heavy quark limit and at a space-like momentum transfer to the weak current, a local operator-product expansion is valid for this correlation function. [...]

Heavy-to-light form factors to three loops / Fael, Matteo (CERN) ; Huber, Tobias (Siegen U.) ; Lange, Fabian (Zurich U. ; PSI, Villigen) ; Müller, Jakob (Siegen U.) ; Schönwald, Kay (Zurich U.) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP)
We compute three-loop corrections of $\mathcal{O}(\alpha_{s}^3)$ to form factors with one massive and one massless quark coupling to an external vector, axialvector, scalar, pseudoscalar, or tensor current. We obtain analytic results for the color-planar contributions, for the contributions of light-quark loops, and the contributions with two heavy-quark loops. [...]

New physics contributions to moments of inclusive b → c semileptonic decays / Fael, Matteo (KIT, Karlsruhe, TTP ; CERN) ; Rahimi, Muslem (Siegen U.) ; Vos, K. Keri (Maastricht U. ; Nikhef, Amsterdam)
Inclusive semileptonic $B\to X_c \ell \bar{\nu}_\ell$ decays, where $\ell = \mu,e$, are by now standard candles in the determination of the CKM element $|V_{cb}|$. These determinations rely on the heavy-quark expansion and use moments of decay spectra to extract the non-perturbative parameters directly from data under the standard model assumption. [...]

Kolya: an open-source package for inclusive semileptonic $B$ decays / Fael, Matteo (CERN) ; Milutin, Ilija S. (Siegen U.) ; Vos, K. Keri (Maastricht U. ; NIKHEF, Amsterdam)
We introduce the code kolya, an open-source tool for phenomenological analyses of inclusive semileptonic $B$ meson decays. [...]

Transversal Modes and Higgs Bosons in Electroweak Vector-Boson Scattering at the LHC / Brass, Simon (Siegen U.) ; Fleper, Christian (Siegen U.) ; Kilian, Wolfgang (Siegen U. ; CERN) ; Reuter, Jürgen (DESY) ; Sekulla, Marco (KIT, Karlsruhe, TP)
Processes where $W$ and $Z$ bosons scatter into pairs of electroweak bosons $W$, $Z$, and Higgs, are sensitive probes of new physics in the electroweak sector. We study simplified models that describe typical scenarios of new physics and parameterize the range of possible LHC results between the Standard-Model prediction and unitarity limits. [...]

We here report on the progress of the HHH Workshop, that took place in Dubrovnik in July 2023. After the discovery of a particle that complies with the properties of the Higgs boson of the Standard Model, all SM parameters are in principle determined. [...]
