Wasserstein normalized autoencoder /CMS Collaboration
A novel approach to unsupervised jet tagging is presented for the CMS experiment at the CERN LHC. The Wasserstein normalized autoencoder (WNAE) is a normalized probabilistic model that minimizes the Wasserstein distance between the probability distribution of the training data and the Boltzmann distribution of the reconstruction error of the autoencoder.

Measurement of the W boson mass in proton-proton collisions at sqrts = 13 TeV /CMS Collaboration
In the standard model of particle physics, the masses of the carriers of the weak interaction, the W and Z bosons, are uniquely related. Physics beyond the standard model can change this relationship through the effects of virtual particle quantum loops, thus making it of paramount importance to measure these masses with the highest possible precision.
