 Integration and testing of the DAQ system for the CMS phase 1 pixel upgrade / Akgun, Bora (Rice U.) /CMS Collaboration The CMS pixel detector phase 1 upgrade in 2017 requires an upgraded DAQ to accept higher data rates. A new DAQ system has been developed based on a combination of custom and standard microTCA parts. [...] CMS-CR-2016-280.- Geneva : CERN, 2016 - 9 p.

 Groomed jets in heavy-ion collisions: sensitivity to medium-induced bremsstrahlung / Mehtar-Tani, Yacine ; Tywoniuk, Konrad We argue that contemporary jet substructure techniques might facilitate a more direct measurement of hard medium-induced gluon bremsstrahlung in heavy-ion collisions, and focus specifically on the "soft drop declustering" procedure that singles out the two leading jet substructures.
