Simple SUSY GUT models based on the gauge group SO(10) require t-b-t Yukawa coupling unification, in addition to gauge coupling and matter unification. The Yukawa coupling unification places a severe constraint on the expected spectrum...
This dissertation describes a measurement of the muon charge asymmetry from W boson decays. The charge asymmetry provides useful information about the momentum distribution of u and d quarks inside the proton. The charge asymmetry was...
We report a study on the magnetotransport properties and on the Fermi surfaces (FS) of the ZrSi(Se, Te) semimetals. Density Functional Theory (DFT) calculations, in absence of spin orbit coupling (SOC), reveal that both the Se and the Te...
In this Thesis we present the Next-To-Leading-Order calculation, O(ααs2), of the inclusive cross section for a photon and a heavy quark (charm or bottom), p bar p / pp γ + Q +X, (Q=c, b) at hadron colliders. We include fragmentation...
Magnetotransport and resistance noise have been studied in high quality singlecrystals of La2Cu1−xLixO4 and La2−xSrxCuO4 with x=0.03. The detailed measurements are performed at temperatures ranging from 0.03 to 190K and in magnetic...
The Weyl semimetal requires the breaking of either the time-reversal symmetry (TRS) or the lattice inversion symmetry. When the TRS and inversion symmetry coexist, a pair of degenerate Weyl points may exist, leading to the related Dirac...
This dissertation presents the first measurement of top quark pair production cross-section in events containing a muon and a tau lepton. The measurement was done with 1 fb−1 of data collected during April 2002 through February 2006...
This dissertation presents a search for large extra dimensions in the single photon plus missing transverse energy final states. We use a data sample of approximately 2.7fb⁻¹ of pp̄ collisions at√s= 1.96 TeV (recorded with the DØ...
We perform a survey of the ( proton K+ K− ), 3 charged track data taken by the CLAS detector for the HyCLAS experiment [1] during the g12 run-period at Jefferson Lab. We aim to study the strong decay amplitudes, partial widths and...
