Research Interests
  • High energy experimental physics and phenomenology; relation between strong and electroweak interactions; determination of parameters of electroweak theory in high energy interactions; search for Higgs and Supersymetric particles
  • Hadron thermodynamics, in high energy nucleon antinucleon interactions; equation of state of super dense hadronic matter; observation of quark-gluon plasma
  • Accelerator physics; beam instabilities, superconducting magnets.
  • Higgs searches using the CERN LHC CMS detector in p-p collisions
Research Activities Physics

The energy of the CERN LEP e + - e - collider has been increased from 100 GeV to 202 GeV. This has opened a new vista in electro-weak physics. We can now study equation W+-W- and Z0 -Z0 pair productions as well as search for Higgs and SUSY particles. Indeed LEP groups observed several Higgs candidate in the e positive e negative right arrowZ+H channel.


Initiated the robotics approach to cathode strip end cap muon chamber construction. To solder 6 million wires under tension we have developed a robotic soldering technique and constructed three non-contact, non-magnetic tension meter. A linear robot moves the computer controlled 64-channel tension meter. The first set of computer and robot controlled soldering, winding and tension meter devices have been operational for sometime. The first linear robot, built at Purdue has been merged with the tension meter and is operating at the FNAL chamber factory for more than two years.

Three large area computer controlled, robotic based wire tension meters have been constructed at the Purdue Central Machine Shop. One of them will be sent to Beijing, China. The second device has been shipped to St. Petersburg, Russia. The first robot is being used to control muon chamber quality as they are produced at Fermilab. We have built the robotic quality control of muon chamber production. They are: computer integrated R and C meters for cathode strips, anode wire quality control via optical and electric methods, computer integrated anode wire capacitance meter, and wire tension and pitch meters.

The Large Hadron Collider (LHC)

Physicists from 30 countries, including the U.S., are building the CMS (Compact Muon Solenoid) experiment to explore the new high-energy frontier that will be opened up when the Large Hadron Collider (LHC) starts up in 2005 at CERN, the European Laboratory for Particle Physics. The Large Hadron Collider (LHC) approved for construction at CERN in Geneva, Switzerland, will be the highest energy particle accelerator in the world on its completion in 2005. The study of the elusive Higgs particle is one of the main goals of the LHC, along with a large increase in the physics reach for a wide variety of processes, including: the search for possible size and substructure in quarks or leptons, the search for new heavy particles such as supersymmetric partners of the known fermions and bosons, and extremely high- statistics studies of systems containing the bottom and top quarks.

Compact Muon Solenoid (CMS)

Purdue Task D is a founding U.S. member of the Compact Muon Solenoid (CMS) collaboration, one of the two general purpose detectors being built for LHC.

Professor Gutay is involved in constructing the LHC-CMS muon detector. A new kind of large area muon detector has been developed. Since both the anode wires and the segmented cathode planes give coordinate readout (r, equation) these new detectors are called cathode strip chambers. Purdue's responsibility is testing the performance of the completed chamber and electronics and the quality control of the chamber construction process. The most interesting problem is the development of large area computer controlled robots to carry out winding, soldering and tension measuring. Purdue has played a major role in the development of the robotics system of the cathode strip chambers in collaboration with our Fermilab and PNP1 colleagues.
