520 3    |a Linear Non-Adiabatic calculations of Cepheids, Type II Cepheids and RR Lyraes by AJ Chalmers, N Proietti, S Das and SM Kanbur. We present extensive grids of Linear Non-Adiabatic calculations of three different types of pulsating stars, classical Cepheids, type II Cepheids and RR Lyraes, made with several different theories of time dependent turbulent convection. We discuss our results and their implications.
520 3    |a D and R Type Ionization Fronts in Classical Cepheids by AJ Chalmers and SM Kanbur. We present a grid of full amplitude non-linear hydrodynamic models of fundamental mode Cepheids and study the nature of the hydrogen ionization front in these models and in particular we examine whether these models indicate any evidence of D to R type transitions during the pulsation cycle.
520 3    |a The Hydrogen Ionization Front-Photosphere optical depth and its use as a way to constrain Horizontal Branch Models of RR Lyraes by N Proietti, S. Das, E. Bellinger and SM Kanbur. RR Lyraes display a flat Period-Color relation at minimum light. Recent work has demonstrated that this is due to the hydrogen ionization front (HIF) and Stellar Photosphere (SPh) being close to each other in terms of optical depth. Here we investigate how this optical depth difference between the HIF and SPh varies in a grid of MESA evolutionary models varying mass, composition and mass loss parameter.
520 3    |a 1D Radiation Hydrodynamic Pulsation Models of RR Lyraes in the Globular Cluster M3 by AJ Chalmers N Proietti, S Das, A Bhardwaj, SM Kanbur. We present an extensive grid of full amplitude 1D radiation hydrodynamic models of RR Lyraes with parameters appropriate for the globular cluster M3. We present the multi-wavelength theoretical light curves and discuss the implications of our results.
520 3    |a Benchmark Tests of the CERN ROOT Framework for the Analysis of Nuclear Physics and Particle Physics Data Sets by Anthony Chalmers, Nicholas Proietti, and Anne Caraley. The use of ROOT as a computational tool for physics research is explored through multiple benchmark tests, preceding the analysis on high energy physics simulation data as a foundation. ROOT is an object-orientated program and library developed by CERN (European Organization for Nuclear Research) for the purpose of handling the massive influx of data generated there at accelerators such as the Large Hadron Collider. ROOT’s potential to assist researchers in nuclear and particle physics will be presented along with results found through analysis with the C++ ROOT framework. The lifetime of the muon is investigated within, utilizing ROOT along with data collected by 2014 Advanced Lab in Nuclear Physics students. A value for the muon lifetime of 2.34 ± 0.02μs was found utilizing histograms and fit functions, which compares favorably with the known value of 2.2μs. Secondly, gamma-ray radiation from an unknown source found in WW II era truck gauges was investigated as a study of energy calibration procedures. The application of seven Gaussian fits to the unknown source’s spectrum was completed using ROOT and the source was identified as radium-226 by comparing results with its known decay chain. After verifying the viability of ROOT as a data analysis tool, data simulating the ATLAS experiment at CERN including over 700,000 proton-proton collisions was investigated to demonstrate its ability further. With this, the spectrum of the W boson’s transverse mass was analyzed in histograms showing an expected cutoff at around 100GeV for both muon-muon-neutrino and electron-electron-neutrino decay schemes. The Z boson was then reconstructed from this data set as well, and a spectrum of its invariant mass was analyzed with ROOT. Both electron and muon based decay schemes were accounted for and values for the Z boson mass are presented as 91.03 ± 0.15GeV for muon-anti-muon decay and 91.01±0.06GeV for electron-positron decay compared to the known value of 91.19GeV. Given more time, this study would be expanded to investigate ROOT’s virtual machine framework for analysis of the Higgs Boson as a further statement to ROOT’s capabilities. These results and the processes taken to obtain them show the accuracy and utility of ROOT as a computational tool in humanity’s quest to discover and understand the universe around us.
520 3    |a Determination of the Mass of the Top Quark Using the CERN ROOT Framework Nicholas Proietti, Anthony Chalmers, Anne Caraley. CERN is a European research organization whose primary mission is to contribute particle accelerators and other high-energy physics research facilities. As a result of international collaborations, several experiments have been developed at CERN, including the Large Hadron Collider (LHC),a large, powerful particle collider that studies the collisions of particles at high speeds. There are eight experiments located along the LHC, with each studying various characteristics of particle collisions. However, there is emerging eagerness over the potential of one of its experiments, the Compact Muon Solenoid (CMS), to test several extensions of the Standard Model. CMS is a general purpose detector that investigates proton-proton collisions as part of a comprehensive initiative that includes studies of Higgs boson physics and other high-precision measurements of the Standard Model, especially the rare processes involving the top quark. First observed in 1995, the top quark is the most massive of the six quarks in the Standard Model. With a mass of173.3GeV /c2, about 175 times heavier than the proton, the top quark’s large mass uniquely lies near the electroweak scale and thus provides the potential for researchers to probe predictions and parameters of the Standard Model through its production and decay. Using a portion of real(50pb-1) CMS collision data at vs= 7T eV collected from 2011, the analysis of top quark discoveries was replicated and understood with ROOT, an open-source data analysis framework used by CERN for high energy physics. The four-vector components of the top quark, such as a b-tagged jet, an isolated muon, and a neutrino, as well as Lorentz frame transformations, were employed to create the mass histograms for the top quark. The determination of the top quark mass from these histograms, with and without the presence of background events, as well as comparisons with simulated top quark invariant mass to investigate other particle contributions to the mass spectrum, will be presented. In addition, investigations related to the Z and W boson masses, whose components were used in the construction of top quark mass histograms, will be discussed. The mass of the top quark was found to be 168±1.8GeV /c2, which compares favorably to the established value of 173.3GeV /c2. The success of this analysis underlines the potential of studying the top quark to probe the coupling of the top quark to the Higgs boson and opens the door for future analyses of publicly available CERN data related to the Higgs boson.
