(16TH Internatinal Symposium on Capture Gamma-Ray Spectroscopy and Related Topics (CGS16), 2018)The paper reviews the systematic studies of triaxial deformations, new mode excitations and shape evolutions with regard to triaxial deformation in the neutron-rich nuclei with Z = 41-46, A similar to 100-116.
-
(Physical Review D, 2019-07-29)Dark matter that is electrically neutral but couples to the electromagnetic current through higher-dimensional operators constitutes an interesting class of models. We investigate this class of models at the Large Hadron ...

(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)In 2012, the collaboration overseeing the Daya Bay Reactor Neutrino Experiment announced results which determined the magnitude of the mixing angle \theta_{13} with unprecedented precision. However, no attempt was made in ...
-
(Astronomical Journal, 2022-12-19)Examination of emission lines in high-velocity-resolution optical spectra of the Orion Nebula confirms that the velocity component on the red wing of the main ionization front emission line is due to backscattering in the ...

(Physical Review C, 2019-08-01)The almost hermetic coverage of the CMS detector is used to measure the distribution of transverse energy, E-T, over 13.2 units of pseudorapidity, eta, for pPb collisions at a center-of-mass energy per nucleon pair of root ...
-
(EUROPEAN PHYSICAL JOURNAL C, 2019-05-20)Combined measurements of the production and decay rates of the Higgs boson, as well as its couplings to vector bosons and fermions, are presented. The analysis uses the LHC proton-proton collision data set recorded with ...
-
Dark Matter benchmark models for early LHC Run-2 Searches: Report of the ATLAS/CMS Dark Matter Forum (Physics of the Dark Universe, 2020-01)This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum organized by the ATLAS and CMS collaborations with the participation of experts on theories of Dark Matter, to select a minimal basis set of ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)Cosmic microwave background (CMB) observations suggest the possibility of an extra dark radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more ambiguous. Dark radiation from a decaying ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)The Compact Muon Solenoid Experiment (CMS) at the Large Hadron Collider (LHC) at CERN has brilliant prospects for uncovering new information about the physical structure of our universe. Soon physicists around the world ...

-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)The Pauli Exclusion Principle places a fundamental limit on the brightness of an electron beam. Developing a cathode which can reach this limit is useful for achieving maximum operation in current applications of ...

-
(Journal of Instrumentation, 2019-06)An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau ...

-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)The study of living specimens is essential to the understanding of organismal behavior. Unfortunately, a major difficulty in the study of live organisms is that many move in and out of the field of view or focal plane ...
-
(Vanderbilt University. Dept. of Physics & Astronomy, 2008)During the course of my Honors Research Project, I worked with Dr. David James to determine whether a group of target stars are members of the Local Association. I did this by reducing spectroscopic data, taken by Dr. ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)Finite element modeling was performed using COMSOL Multiphysics to study the thermal dynamics of gold::vanadium dioxide (VO$_{2}$) nanocomposites. These simulations were done to understand the data from transient ...
-
(ASTRONOMY & ASTROPHYSICS, 2019-07-22)We present an elemental abundance analysis of high-resolution spectra for five giant stars spatially located within the innermost regions of the bulge globular cluster NGC 6522 and derive Fe, Mg, Al, C, N, O, Si, and Ce ...
-
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)Electron microscopy has been the recent subject of molecular imaging due to the strength of the electrons' interaction with the target molecule making for a detailed pattern at a small scale.[1] To achieve the best 4D ...
