In this paper we give an extensive description of Weyl quadratic gravity as the gauge theory of the Weyl group. The previously discovered (vectorial) torsion/non-metricity equivalence is shown to be built-in as it corresponds to a redefinition of the generators of the Weyl group. We present a generalisation of the torsion/non-metricity duality which includes, aside from the vector, also a traceless 3-tensor with two antisymmetric indices and vanishing skew symmetric part. A discussion of this relation in the case of minimally coupled matter fields is given. We further point out that a Rarita-Schwinger field can couple minimally to all the components of torsion and some components of non-metricity. Alongside we present the same gauge construction for the Poincar\'e and conformal groups. We show that even though the Weyl group is a subgroup of the conformal group, the gauge theory of the latter is actually only a special case of Weyl quadratic gravity.

World-Line Actions in Weyl Geometry
A dimensionless Weyl-invariant additive world-line action exists for time-like particles in Weyl geometry, but proper time cannot be defined until scale symmetry breaks.

Weyl gauge symmetry at LIGO-Virgo-KAGRA
In Weyl quadratic gravity linearized around de Sitter space, gravitational waves carry two tensor modes plus two transverse vector modes from the Weyl gauge field, with no scalar modes.

Conformal geometry as a gauge theory of gravity: covariant equations of motion & conservation laws
The most general Weyl-quadratic-gravity action yields manifestly gauge-covariant equations of motion, with energy-momentum and Weyl-current conservation holding in both the Weyl and Riemannian pictures.

The fall and the rise of Weyl gauge theory
Weyl quadratic gauge gravity is anomaly-free, breaks via Stueckelberg to Einstein-Hilbert plus positive Lambda, and is the leading order of a regulator-free WDBI action that can include the SM.
