Search for heavy neutral Higgs bosons A and H in the $ {\mathrm{t}\overline{\mathrm{t}}} $Z channel in proton-proton collisions at 13 TeV
A direct search for new heavy neutral Higgs bosons A and H in the $ {\mathrm{t}\overline{\mathrm{t}}} \mathrm{Z} $ channel is presented, targeting the process $ \mathrm{p}\mathrm{p}\to\mathrm{A}\to\mathrm{Z}\mathrm{H} $ with $ \mathrm{H}\to{\mathrm{t}\overline{\mathrm{t}}} $. [...]

Search for heavy scalar or pseudoscalar states in $\mathrm{t \bar{t}}$ events at CMS / Jeppe, Laurids (DESY)
A search for scalar or pseudoscalar states decaying to a top quark-antiquark pair ($\mathrm{t \bar{t}}$), using $138\,\mathrm{fb}^{-1}$ of pp collision data taken at $\sqrt{s} = 13\,\mathrm{TeV}$ using the CMS detector, is presented. [...]

Renormalisation group evolution of the shape function $g_{17}$ in $\bar{B}\to X_s \gamma$ and $\bar{B} \to X_s \ell^+\ell^-$ at subleading power / Bartocci, Riccardo (U. Mainz, PRISMA ; Mainz U., Inst. Phys.) ; Böer, Philipp (CERN) ; Hurth, Tobias (U. Mainz, PRISMA ; Mainz U., Inst. Phys.)
We derive and solve the renormalisation-group (RG) equation of the shape function $g_{17}(\omega,\omega_1;\mu)$, which appears at subleading power in the factorization of the inclusive decays $\bar{B} \to X_s \gamma$ and $\bar B \to X_s \ell^+\ell^-$. [...]

First TeV upper limits on the 0.1s short bursts of magnetar SGR 1935+2154 with the CTAO LST−1 /RE23/CTA-LST Collaboration
Aims. We report on the observations of the Soft Gamma Repeater (SGR) 1935+2154 performed with the Large-Sized Telescope prototype (LST−1) of the Cherenkov Telescope Array Observatory (CTAO) during periods of high-energy (HE) activity from the source. [...]

GRB 221009A: Observations with LST-1 of CTAO and implications for structured jets in long gamma-ray bursts /RE23/CTA-LST Collaboration
GRB 221009A was the brightest gamma-ray burst (GRB) observed to date. Extensive coverage of its afterglow emission across the electromagnetic spectrum was performed, providing the first strong evidence of a jet with nontrivial angular structure in a long GRB. [...]
