The first 10 columns are the low level features, followed by the 15 high level features that can derived from these low level quantities. Each row describes a sample. Attribute Information: Low-level: -The three-dimensional momenta, $p$, of the charged leptons. -The imbalance of transverse momentum ($\missET$) in the final state transverse to the beam direction, due to unobserved or mismeasured particles. -The number and momenta of particle `jets' due to radiation of gluons or quarks. High-level: -Axial missing momentum, $\missET\cdot p_{\ell^+\ell^-}$. -Scalar sum of the observed momenta, $|p_{\ell^+}|+|p_{\ell^-}|+|\missET|+\sum_i |p_{\textrm{jet}_i}|$. -Relative missing momentum, $\missET$ if $\Delta\phi(p,\missET)\ge\pi/2$, and $\missET\times\sin(\Delta\phi(p,\missET)$ if $\Delta\phi(p,\missET)<\pi/2$, where $p$ is the momentum of any charged lepton or jet. -Difference in lepton azimuthal angles, $\Delta\phi(\ell^+,\ell^-)$. -Difference in lepton polar angles, $\Delta\eta(\ell^+,\ell^-)$. -Angular distance between leptons, $\Delta R=\sqrt{(\Delta\eta)^2+(\Delta\phi)^2}$; -Invariant mass of the two leptons, $m_{\ell^+\ell^-}$. -Missing mass, $m_{\textrm{MMC}}$~\cite{Elagin:2010aw}. -Sphericity and transverse sphericity. -Invariant mass of all visible objects (leptons and jets).
