Phenomenological issues in the determination of Delta Gamma(D)
D0 Δ Γ D experiments D0 decay model phase difference cleo
2014/12/22
We consider the issue of determining the D0– width difference ΔΓD experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D0 decay modes i...
Determination of <(pi pi)I=2/ohm 7,8/K0 > in the chiral limit
Weak matrix elements no cover dispersion
2014/12/22
We reconsider the dispersive evaluation of the weak matrix elements h()I=2|Q7,8|K0i in the chiral limit. The perturbative matching is accomplished fully within the scheme dependence used in the two ...
Improved determination of the electroweak penguin contribution to epsilon '/epsilon in the chiral limit
Energy opal spectral function and matrix element electroweak penguin operators
2014/12/20
We perform a finite energy sum rule analysis of the flavor ud two-point VA current correlator, (Q2). The analysis, which is performed using both the ALEPH and OPAL databases for the V-A spectral fun...
Very High Precision Determination of Low-Energy Parameters: The 2-d Heisenberg Quantum Antiferromagnet as a Test Case
Very High Precision Determination of Low-Energy Paraameters 2-d Heisenberg Quantum Antiferromagnet Test Case
2011/1/14
The 2-d spin 1 2 Heisenberg antiferromagnet with exchange coupling J is investigated on a periodic square lattice of spacing a at very small temperatures using the loop-cluster algorithm. Monte Carlo ...
Helium fine structure theory for determination of \alpha
Helium fine structure theory determination
2010/11/16
We present recent progress in the calculation of the helium fine-structure splitting of the 2^3P_J states, based on the quantum electrodynamic theory. Apart from the complete evaluation of m\alpha^7 ...
Strain determination in the Si channel above a single SiGe island inside a field effect transistor using nanobeam x-ray diffraction
Strain determination Si channel field effect transistor
2010/11/24
SiGe islands are used to induce tensile strain in the Si channel of Field E ect Transistors to achieve larger transconductance and higher current driveabilities. We report on x-ray di raction experime...
A model-insensitive determination of First-hitting-time densities with Application to Equity default-swaps
First-hitting-time densities Equity default-swaps
2010/4/27
Equity default-swaps pay the holder a fixed amount of money when the underlying spot level touches a (far-down) barrier during the life of the instrument. While most pricing models give reasonable res...
