This book was released on 2015 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research field of this work is experimental nuclear physics. I use data taken with the Solenoidal Tracker At RHIC (STAR) experiment at the Relativistic Heavy Ion Collider (RHIC), an accelerator facility located at Brookhaven National Laboratory (BNL) in Long Island, NY. RHIC accelerates beams of protons, light and heavy ions (e.g. Au nuclei) to relativistic velocities and collides them. The collisions compress and heat the nuclear matter to very high temperatures and densities, over one trillion degrees Celsius. Under such conditions a phase transition might occur in nuclear matter, a transition, where quarks and gluons become de-confined, i.e. free to move around, forming the so-called Quark Gluon Plasma (QGP). The study of the properties of QGP, its properties and dynamics, provide a deeper understanding of Quantum Chromo-Dynamics (QCD), the theory of strong force, and the conditions in the early universe. A key finding by the experiments at RHIC is the unexpected strong suppression of heavy flavor at high transverse momentum values in Au+Au relative to elementary proton-proton collisions. Heavy quarks are mainly produced during the early stages of the collision when the most energetic interactions occur. The suppression of heavy flavor particles is caused by their interaction with the produced medium, as they traverse it. Charm and bottom quark production can be used as a tool to better probe the matter created during the early phases of the collision. The available theoretical models at that time under-predicted the observed suppression. In order to better understand the observed phenomenon and the details of the interaction between heavy flavor quarks and the hot nuclear medium, precision measurements of mesons containing charm or bottom quarks needed to be performed by the experiments. Heavy flavor mesons are unstable particles and most of them decay weakly within the first millimeter from the production vertex. Their relative low production rates, low branching ratios (B.R.) to useful channels and short lifetimes (ctau), e.g. D0 -> K¿ + pi (B.R. = 3.89% and ctau = 123μm) makes their reconstruction a challenging task. One needs a very-high precision vertex detector in order to separate the decay products from the thousands of particles produced in the collision. The STAR collab- oration built such a detector, the Heavy Flavor Tracker (HFT) with state-of-the-art silicon pixel technology. The HFT gives us the track pointing precision required to efficiently reconstruct charm and bottom meson decay vertices from background. The work in this Thesis is concentrated around the track pointing performance of HFT, sometimes called DCA (Distance of Closest Approach). More specifically we studied the HFT performance using data taken during its first physics run, Run14, that took place in 2014. We present and discuss the details of our analysis methods and the obtained results. We demonstrate that the HFT achieved and exceeded its original design goals in terms of track pointing resolution.

Book excerpt: We propose to construct a Heavy Flavor Tracker (HFT) for the STAR experiment at RHIC. The HFT will bring new physics capabilities to STAR and it will significantly enhance the physics capabilities of the STAR detector at central rapidities. The HFT will ensure that STAR will be able to take heavy flavor data at all luminosities attainable throughout the proposed RHIC II era.

Available in PDF, EPUB and Kindle. Book excerpt: For the 2014 heavy ion run of RHIC a new micro-vertex detector called the Heavy Flavor Tracker (HFT) was installed in the STAR experiment. The HFT consists of three detector subsystems with various silicon technologies arranged in 4 approximately concentric cylinders close to the STAR interaction point designed to improve the STAR detector's vertex resolution and extend its measurement capabilities in the heavy flavor domain. The two innermost HFT layers are placed at radii of 2.8 cm and 8 cm from the beam line. These layers are constructed with 400 high resolution sensors based on CMOS Monolithic Active Pixel Sensor (MAPS) technology arranged in 10-sensor ladders mounted on 10 thin carbon fiber sectors to cover a total silicon area of 0.16 m2. Each sensor of this PiXeL ("PXL") sub-detector combines a pixel array of 928 rows and 960 columns with a 20.7 [mu]m pixel pitch together with front-end electronics and zero-suppression circuitry in one silicon die providing a sensitive area of ~3.8 cm2. This sensor architecture features 185.6 [mu]s readout time and 170 mW/cm2 power dissipation. This low power dissipation allows the PXL detector to be air-cooled, and with the sensors thinned down to 50 [mu]m results in a global material budget of only 0.4% radiation length per layer. A novel mechanical approach to detector insertion allows us to effectively install and integrate the PXL sub-detector within a 12 hour period during an on-going multi-month data taking period. The detector requirements, architecture and design, as well as the performance after installation, are presented in this paper.

Book Synopsis Neutrino Hunters by : Ray Jayawardhana
Download or read book Neutrino Hunters written by Ray Jayawardhana and published by Harper Collins. This book was released on 2013-12-10 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The incredibly small bits of matter we call neutrinos may hold the secret to why antimatter is so rare, how mighty stars explode as supernovas and what the universe was like just seconds after the big bang. They even illuminate the inner workings of our own planet. For more than eighty years, adventurous minds from around the world have been chasing these ghostly particles, trillions of which pass through our bodies every second. Extremely elusive and difficult to pin down, neutrinos are not unlike the brilliant and eccentric scientists who doggedly pursue them. Ray Jayawardhana recounts in Neutrino Hunters a captivating saga of scientific discovery and celebrates a glorious human quest, revealing why the next decade of neutrino hunting could redefine how we think about physics, cosmology and our lives on Earth.
