RPC´s Data AnalysesCOMPUTING wtihin M&O A GEM project
- 5 PhD students have participated in different stages of the RPC´s between 2006 and 2013.
- Comissioning and operation, debugging of problems, HV Scans, Detector efficiencies, Prompt analysis tools, etc.
This has been our hardware contribution to CMS and our pkan is to continue with it.
2 PhD theses completed:
1. C. Carrillo: “Search for heavy stable charged particles in the CMS experiment using the RPC detectors”. Advisors: J.C. Sanabria, M. Maggi.
2. A. Ocampo: “Search for supersymmetry production signals in events with two leptons with the same sign using the cms detector”, Advisors: B. Gomez, M. Maggi.
2 PhD theses in progress:3. Luisa Chaparro: “Search for the Dalitz Decay of the Higgs Boson in p-pCollisions with the CMS Detector”, Advisors. J. C. Sanabria, C. Cariillo.4. J. P. Gomez: “Search for stops in theCMS experiment, reducing tt bar background with matrix elements techiniques”, Advisors: C. Avila, M. Maggi.
1 PhD thesis tin the SUSY VBF group: A. Cabrera.
9 engineers from our university have taken part of the computing operations groupd of CMS, during the period 2006-2014.Each of them with a stay of 2 years.They have been hired within the M&O A scheme. Two enginners have also been involved in the LPC at Fermilab. Duties are directly defined by the CMS computing group.
Important activity for the visibility of our engineers and our university.
We are just starting: We have assembled one GEM detector in our lab and are ready to start performing some tests.
We could also try to get involved one MSc student in simulation.
2 MSc Thesis (Carlos Bula, I. Caicedo). 3 undergraduate thesis (C. Roa, S. Castro, I. Caicedo.)

Detector Conditions Data Distribution
Support for the Frontier system, which distributes detector conditions data throughout the WLCG (Worldwide LHC Computing Grid).
Support for the associated WLCG Squid network, deployed to decrease load on central Frontier servers.
Implementation of the mandate of the WLCG Squid Monitoring Taskforce, encompassing CMS, ATLAS and the CVMFS system.
Tracking, debugging and monitoring of workflows
Improving and developing monitoring scripts and tools
21C. Avila, UNIANDESJanuary 8th 2014
Computing Workflow Management
Daily operations of the CMS computing jobs distribution system, GlideinWMS.
Deployment and updating of WMAgent software for CMS Workflows management.
Daily operations of the CMS Dataset Book-keeping Service (DBS), currently transitioning from v2 to v3.

HELEN and EPLANET are finished. We need a new international project. This is important for mobility of students, postdoc and professors.
GOALS & PERSPECTIVES FOR 2014
1. Continue our activities in MEDIPIX with new MSc student in collaboration with the bio-engineering department and other Colombian universities.
2. Continue our participation in the RPCs
3. Maintain the participation of our engineers in the CMS computing M&O A program.
4. Finish thesis of Juan Pablo Gómez on stop search with t-tbar background reduction with matrix elements method.
5. Advance with thesis of Luisa Chaparro on Higgs dalitz decay.
6. Start thesis of Andres Cabrera on SUSY VBF with muons in final state This thesis will help to pave the way for our collaboration with Texas A&M and Vanderbilt.
7. Start our contribution to the GEM project. Collaboration with Texas A&M and Vanderbilt seems positive.
8. We have also interest in participating in a SUSY phenomenology- experimental project in collaboration with Texas A&M and Vanderbilt Possibly with new PhD student Felipe Gonzalez.
9. Need to write some inernal notes for the work done by our group, including service work and theses of our students.
10. Need to find new external sources to finance our activities, specially mobility.
