Tariq Aziz obtained his MSc (1974) and PhD(1979) from Aligarh Muslim University. He joined TIFR, Mumbai in 1979 and since then he has continued to be at TIFR in various capacities, including Chair, Department of High Energy Physics. Currently he is Senior Professor at TIFR. He has served various committees of DAE and DST relevant to high energy particle physics programs. He has been chair, planning committee, SERC school in EHEP for several years. Tariq Aziz has been visiting scientist at various international institutions. He was visiting scientist at I.Physics Institute, Aachen (1986-87), Aachen & CERN (1991-92) and CERN Associate (2001-02). Also he made numerous short visits to centers of accelerator based high energy physics. He has been leader of his team participating in major collaboration experiments like the CMS experiment at LHC and Belle & Belle-II experiment at KEK B-Factory, where he is also member of the collaboration boards. He has been invited member of the European Strategy Group for medium term and long term program of CERN.
Tariq Aziz has been involved in three major collaboration experiments. The L3 collaboration at CERN, the Belle & Belle-II collaboration at KEK and the CMS collaboration at CERN
The L3 collaboration experiment at the Large Electron Positron Collider (LEP) at CERN, Geneva to study Z-boson properties, heavy flavor physics via Z at LEP-I and WW, ZZ production and search for Higgs boson via HZ production at LEP-II. A precise measurement of the number of light neutrino species by this experiment is fundamental to understand the fabric of our universe. He played a key role in building forward part of the L3 hadron calorimeter and later L3 forward muon detector. He established Neural Network and demystified it at an early stage for physics analysis. He introduced several innovative physics variables to improve b-quark jet tagging that were important to study Z boson properties and b-flavored physics. At LEP-II phase he introduced special physics variable to tackle 4-Jet events where QCD 4-jets could fake boson pair production and Higgs production via ZH, thus improving Higgs boson mass search at LEP-II, including search for BSM Higgs.
The Belle collaboration Experiment at KEK B factory (asymmetric electron-positron collider) dedicated to B-Physics, CP-violation, Rare decays and search for new states. The CP-violation results from this experiment confirmed the Kobayashi–Maskawa paradigm of CP-violation in B-meson system and led to the Nobel Prize to M. Kobayashi and T. Maskwa. He has been involved in several rare B-meson decay studies that are relevant for physics at high mass scales, even beyond the direct reach of LHC. For next phase at SuperKEKB, he is involved in building one of the most sophisticated Silicon Vertex Detector, the inner high resolution tracking system of Belle-II. During the R&D phase, he developed high resolution AC coupled silicon microstrip sensors in India for the first time. This R&D has been carried out in association with BHEL, Bangluru over several years to match the world class sensors of this kind. For this purpose he setup advanced Silicon Detector Lab at TIFR.
The CMS collaboration experiment at Large Hadron Collider (LHC), the highest energy frontier, to search for Higgs boson and possible new physics. The observation of the Higgs boson at a mass of 125 GeV confirmed the Higgs mechanism of mass generation and led to the Nobel Prize to P. Higgs and F.Englert. He has been involved in search for exotic Higgs-like objects in high mass range where these objects can lead to WW production where W boson gets such a high boost that the two possible jets from W merge and form single fat jet. Understanding such events with special techniques improves the LHC reach for new physics.
