Dear organizers,
on behalf of the CMS conference committee I would like to submit
another abstract from CMS. We believe the topic is very relevant and
matches the scope of TIPP2014. We apologize for the delay in
submission, we hope very much this contribution can still be included
in your program:
Luminosity measurement at CMS
The measurement of the luminosity delivered by the LHC is pivotal for
several key physics analyses. During the first three years of running,
tremendous steps forwards have been made in the comprehension of the
subtleties related to luminosity monitoring and calibration, which led
to an unprecedented accuracy at a hadron collider. The detectors and
corresponding algorithms employed to estimate online and offline the
luminosity in CMS are described. Details are given concerning the
procedure based on the Van der Meer scan technique that allowed a very
precise calibration of the luminometers from the determination of the
LHC beams parameters. What is being prepared in terms of detector and
online software upgrades for the next LHC run is also summarized.
Best regards,
Marco
