Velasco's Group
 

Within the Northwestern University High Energy Physics Group, the Velasco research group is currently working on several ongoing particle physics projects at the European Laboratory for Particle Physics (CERN). 

  • Currently teaching
  • Projects

    • CMS
    The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors being built on the proton-proton Large Hadron Collider (LHC) at CERN in Switzerland. Approximately 2600 people from 180 scientific institutes form the collaboration building it. The completed detector will be cylindrical, 21 metres long and 16 metres diameter and weigh approximately 12,500 tonnes. Our group focuses on the Hadronic Calorimeter  and it performance.

    Other CMS efforts at Northwestern are lead by Prof. Michael Schmitt (muon system)  and Prof. Bruno Gobbi (foward pixel).

    Linear Collider R&D
    This research is fully supported by the Illinois Consortium for Accelerator Research (ICAR)

    •   CTF3 facility at CERN which is devoted to study dual beam acceleration for the CLIC-project
                                     "The feasibility of the CLIC concept could be demonstrated by 2010,
                                       assuming appropriate resources were made available."
In collaboration with LLNL and SLAC

NA48

FINISH:  NA48-01 , studying rare kaon and neutral hyperon decays from the k-short using the NA48 SPS K12 beam-line. In preparation is NA48-02 , to measure CP-violating asymmetry by studying kaon decays from a charged beam.

NA59

    FINISH: Study of the use of a crystal as a 'quarter-wave plate' to produce high energy circularly polarized photons, and the development of new polarimetry techniques for the next Linear Collider. Experiment is taking place at European Laboratory for Particle Physics (CERN)
     
  • People:

    • Mayda Velasco
    Associate Professor, Northwestern University 
    Mayda Velasco's research on high-energy particle physics is currently centered around  tthe CMS and CTF3-CLIC collaborations at the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland. Mayda Velasco is analysis coordinator for semi-leptinc decays at NA48-2, the spokesperson for the NA59, and co-convener for HCAL Detector performance group at CMS.  CV  and publicvation list    for Velasco.

Radek Ofierzynki
Postdoctoral Fellow
Radek is an expert of the calibration of the Electromagnetic and  Hadronic Calorimeters at CMS.  He has work on electroweak physics at LEP as a graduate student and LHC as a CERN Fellow.

    Michal Szleper
    Postdoctoral Fellow... Now at Warsaw CMS group.
    Michal current effor was mostly focus on CMS, with specila attention to the Hadronic Calorimeteyr issues. Michal's past contribution  includes:  the ground motions studies at FNAL needed for future linear colliders,  beam instrumentation and Higg searches and precision measurements at future  Photon Collider. Michal was also involved in the analysis of semileptonic decays in charged kaons at NA48-2 2003. 

Thibaut Lefreve
Postdoctoral Fellow  ... Now a CERN STAFF .
Thibaut works  on the CTF3 facility at CERN which is devoted to study dual beam acceleration for the CLIC-project. He is an expert on beam instrumentation.

Armen Apyan
Postdoctoral Fellow
Armens projects include work on NA59, and the Photon Collider.  At the moment most of his effort is focus on beam dynamic studies for linear colliders and his is using his expertice on coherent phenomena of photon emission by electrons in align crystal to design a more efficient source of polarized positrons.

    Steve Won
    Graduate student
    Steve will do his PhD work based on the first data  from CMS at the LHC collider. He is acquiring expertise on the hadronic calorimeter.

    Teresa Fonseca Martin
    Graduate student ...  Now a CERN fellow at CERN working with the ATLAS group.
    Teresa completed her undergraduate degree in physics, with a specialization in particle physics , at Santiago de Compostela University, Spain. She has worked on NA59 at CERN , and in 2000 received a fellowship from "Fundacion Pedro Barrie de la Maza" to start the Ph.D. program at Northwestern University. She was working on the LKR calorimeter readout for the NA48 experiment at CERN , and doing analysis for Ks decays. Her thesis was in the first observation of    the rare Ks to pi0 mu mu decay -- THESIS. 

    Anne Dabrowski
    Graduate student...  Now a CERN fellow at CERN working with the CLIC-CTF3 group.
    Anne's first project was in the development and testing of New Radiation Ionization Chambers and Secondary Emission Monitors and is becoming and expert in beam instrumentation with the CLIC/CTF3 group. She is also a member of the  NA48 experiment at CERN and is finilazing her thesis work on the Vus measurement from charged Kaon Decays  -- THESIS . 

    Matthew Wood
    Predoctoral Fellow  ... Now a PhD student in Astro-Physics @ UCLA. 

    Mengkai Shieh
    Undergraduate physics major... Now in medical school at Stanford.
