  We study the Drell-Yan process mediated by a new bosonic resonance at the
LHC. The bosons of spin-0, 1, and 2 with the most general leading-order
couplings to Standard Model fermions and gluons are considered, which provide a
model-independent formulation for future exploration of the resonance
properties, such as its spin, mass and couplings. In the case of neutral
resonances, we demonstrate how the shapes of the kinematical distributions
change as one varies the chiral couplings of the quarks and leptons, and show
how to analyze the couplings by making use of the forward-backward asymmetry.
In the case of charged resonances, we propose a novel technique to effectively
reconstruct the angular distribution in the center-of-mass frame, to a large
extent avoiding the two-fold ambiguity due to the missing neutrino. Similar to
the case of a neutral resonance, the spin information of the resonance can be
extracted unambiguously, and chiral couplings and the asymmetries can be
explored in a statistical manner. With the current LHC data, we present bounds
on the mass and cross section times branching fraction of the new resonance and
estimate the future reach.
