abstract
Effective Lagrangians can be used to parametrize the effects of physics beyond the standard model. Assuming the complete theory is a gauge theory, we determine which effective operators may be generated at tree level, and which are only generated at loop level. The latter are be suppressed by factors of $1/ 16\pi^2$ and will therefore be quite difficult to detect. In particular, all operators changing the Standard-Model structure of the triple-gauge-vector couplings fall into this category. We also point out that in certain cases, dimension-eight operators may be more important than dimension-six operators. We discuss both the linear and non-linear representation of the Higgs sector.

Nucleon energy correlators access linear effects from light-quark dipole operators via azimuthal asymmetries in the target fragmentation region at the EIC.
Re-enumeration of dimension-six SM operators yields 59 independent terms (15+19+25) when baryon number is conserved, versus 80 previously.
A z=6.64 Little Red Dot host shows an AGN-driven ionised outflow reaching ~5500 km/s FWHM, with low mass-loading and clear LRD spectral signatures in the compact nucleus.
Collision-induced QED radiation produces O(1) corrections to DIS cross sections but only few-percent shifts in longitudinal electron spin asymmetries, making asymmetries more robust for SMEFT constraints at SoLID and EIC.
Complete NLO QCD corrections to charmless inclusive non-leptonic B-decay widths are computed for the full BSM operator set, yielding 26 constrained directions in Wilson coefficient space.
Consistent NLO power counting in HEFT for di-Higgs gluon fusion requires higher-dimensional operators beyond leading order, affecting kinematic benchmarks used in experiments.
HEFT admits two consistent power counting schemes, one with a single low-energy scale v and one with two scales v < f, each allowing systematic truncation of operators and amplitudes for any normalization choice.
A high-energy muon collider can set stronger limits on d=6 SMEFT operators for b-quark electroweak dipoles than existing EW precision data or B to Xs gamma measurements by studying bb and bbh final states.
