There is a long standing dilemma about the value of photon momentum in dielectric media. Two rivaling views differ on both the magnitude and the direction of momentum but both are seemingly sound from a theoretical standpoint. Experimental work done also has evidence favoring both Abraham and Minkowski theories with different experiments supporting one of them. Aim of this thesis is to measure the deflection of a silica fiber filament with an angled end face and measure the displacement resulting from the momentum transfer between the fiber and air interface. The results found are within the error margins predicted by the Minkowski theory. Since the error margins are relatively large, the results are not conclusive enough to disprove the Abraham theory, however they are in strong favor of the Minkowski theory.

Search for Physics Beyond the Standard Model in Events with High-Momentum Higgs Bosons and Missing Transverse Momentum in Proton-Proton Collisions at 13 TeV Sirunyan, A. M.; et. al. (2018-06-01) A search for physics beyond the standard model in events with one or more high-momentum Higgs bosons, H, decaying to pairs of b quarks in association with missing transverse momentum is presented. The data, corresponding to an integrated luminosity of 35.9 fb(-1), were collected with the CMS detector at the LHC in proton-proton collisions at the center-of-mass energy root s = 13 TeV. The analysis utilizes a new b quark tagging technique based on jet substructure to identify jets from H -> b (b) over bar. Ev...
Determination of the g(V sigma gamma) coupling constant through theprocess gamma plus N -> N plus V with circularly polarized photons Rekalo, MP; Tomasi-Gustafsson, E (Elsevier BV, 2003-02-24) We suggest to measure the t-dependence of the two possible T-even asymmetries for the photoproduction of vector mesons, gamma + rho --> rho + V-0, V-0 = rho or omega, in the collision of circularly polarized photons with a polarized proton target. In the framework of a (pi + sigma)-model, these asymmetries are very sensitive to the relative role of pi- and sigma-exchanges, in the near threshold region.
DETERMINATION OF OPTIMUM INJECTED CURRENT PATTERNS IN ELECTRICAL-IMPEDANCE TOMOGRAPHY KOKSAL, A; Eyüboğlu, Behçet Murat (IOP Publishing, 1995-08-01) The problem of finding the optimum current under different constraints in electrical impedance tomography is cast into a non-linear optimization problem. Optimum currents are investigated for a two-dimensional cylindrical body with a concentric or an eccentric inhomogeneity under the constraints of constant dissipated power and constant total injected current. For a concentric inhomogeneity, it is shown that the opposite drive results in a better distinguishability than the cosine current pattern under the ...
Measurement of isolated photon production in pp and PbPb collisions at root s(NN)=2.76 TeV Chatrchyan, S.; et. al. (Elsevier BV, 2012-04-01) Isolated photon production is measured in proton-proton and lead-lead collisions at nucleon-nucleon centre-of-mass energies of 2.76 TeV in the pseudorapidity range vertical bar eta vertical bar < 1.44 and transverse energies E-T between 20 and 80 GeV with the CMS detector at the LHC. The measured ET spectra are found to be in good agreement with next-to-leading-order perturbative QCD predictions. The ratio of PbPb to pp isolated photon E-T-differential yields, scaled by the number of incoherent nucleon-nucl...
Measurement of the weak mixing angle with the Drell-Yan process in proton-proton collisions at the LHC Chatrchyan, S.; et. al. (2011-12-01) A multivariate likelihood method to measure electroweak couplings with the Drell-Yan process at the LHC is presented. The process is described by the dilepton rapidity, invariant mass, and decay angle distributions. The decay angle ambiguity due to the unknown assignment of the scattered constituent quark and antiquark to the two protons in a collision is resolved statistically using correlations between the observables. The method is applied to a sample of dimuon events from proton-proton collisions at roo...
