abstract
This is a pedagogical introduction into theories with branes and extra dimensions. We first discuss the construction of such models from an effective field theory point of view, and then discuss large extra dimensions and some of their phenomenological consequences. Various possible phenomena (split fermions, mediation of supersymmetry breaking and orbifold breaking of symmetries) are discussed next. The second half of this review is entirely devoted to warped extra dimensions, including the construction of the Randall-Sundrum solution, intersecting branes, radius stabilization, KK phenomenology and bulk gauge bosons.

Supersymmetry can stabilize an ultralight dilaton dark matter candidate, but gravity restricts its Standard Model couplings to undetectable levels, making consistent model building involved.
Higher-curvature corrections in a warped braneworld produce an upward shift in KK graviton masses, mildly altered couplings, suppressed virtual production cross sections, and enhanced dilepton/diphoton decay widths.
This review summarizes tidal Love numbers and dissipation effects for black holes, neutron stars, and exotic objects, noting vanishing static bosonic Love numbers for black holes in GR but nonzero values for fermions and exotic objects, with implications for gravitational-wave astronomy.
