Overview of $B \to K^{(*)}\ell \ell$ Theoretical Calculations and Uncertainties
/ Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris) ; Monceaux, Y. (IP2I, Lyon)
The search for New Physics (NP) beyond the Standard Model (SM) has been a central focus of particle physics, including in the context of $B$-meson decays involving $b \to s \ell \ell$ transitions. These transitions, mediated by flavour-changing neutral currents, are highly sensitive to small NP effects due to their suppression in the SM. [...]

$\mathrm{D}$ and $\mathrm{D_s}$ decay constants in $N_{\rm f}=2+1$ QCD with Wilson fermions

/RQCD Collaboration ; ALPHA Collaboration
We present results for the leptonic decay constants of the D and D$_{\rm s}$ mesons from $N_{\rm f}=2+1$ lattice QCD. We employ a set of 49 high statistics gauge ensembles generated by the Coordinated Lattice Simulations (CLS) effort utilising non-perturbatively improved Wilson fermions and the tree-level Symanzik improved gauge action at six values of the lattice spacing in the range $a = 0.098\,$fm down to $a = 0.039\,$fm, with pion masses varying from around $420\,$MeV down to below the physical point.

Probing Neutral Triple Gauge Couplings via $\boldsymbol{Z\gamma\,(\ell^+\ell^-\gamma)}$ Production at $\boldsymbol{e^+e^-}$ Colliders
/ Liu, Danning (Shanghai Jiao Tong U.) ; Xiao, Rui-Qing (Shanghai Jiao Tong U. ; King's Coll. London) ; Li, Shu (Shanghai Jiao Tong U. ; Maryland U. ; Peking U., CHEP) ; Ellis, John (Shanghai Jiao Tong U. ; King's Coll. London ; CERN) ; He, Hong-Jian (Shanghai Jiao Tong U. ; Peking U., CHEP) ; Yuan, Rui (Shanghai Jiao Tong U.)
Neutral triple gauge couplings (nTGCs) are absent in the Standard Model (SM) and at the dimension-6 level in the Standard Model Effective Field Theory (SMEFT), arising first from dimension-8 operators. As such, they provide a unique window for probing new physics beyond the SM. [...]
