The Upgraded CMS Calorimeter Trigger for LHC Run II and a Search for
New Physics in Dijet Angular Distributions at 13 TeV

The Run II era of the CERN Large Hadron Collider (LHC) has begun with
an increased center-of-mass energy of 13 TeV, and with instantaneous
luminosity approaching 2e34 Hz/cm^2 in 2016. To achieve the physics
goals of the experiment in the Run II LHC environment, the trigger
system had be upgraded. In particular the Level-1 calorimeter trigger
hardware from Run-1 has been replaced with an entirely new system
which is based on high performance Xilinx Virtex-7 FPGAs and hundreds
of high-speed optical links operating at up to 10 Gb/s to maximize
data throughput. The design of the L1 calorimeter trigger, and the
optimisation and performance of the trigger algorithms developed to
cope with the high event rates in Run II will be discussed. Recent
results of a search for quark contact interactions and extra spatial
dimensions using measurements of dijet angular distributions with a
dataset corresponding to 2.6/fb at 13 TeV will also be presented.
