Widths of resonances above an energy-level crossing

نویسندگان

چکیده

We study the existence and location of resonances a 2×2 semiclassical system coupled Schrödinger operators, in case where two electronic levels cross at some point, one them is bonding, while other anti-bonding. Considering energy just above that crossing, we find asymptotics both real parts imaginary close to such energies. This continuation our previous works considered around crossing.

Masses, widths, and leptonic widths of the higher upsilon resonances.

The masses, total widths, and leptonic widths of three triplet s-wave bb states Y(4S), Y (5S), and Y(6S) are determined from measurements of the e+e annihilation cross section into hadrons for 10.55 & W & 11.25 GeV. The resonances are identified from potential model results and their properties are obtained with the help of a simplified coupled-channels calculation. We find M(4S) = 10.577 GeV, ...

Pion-pion Scattering above Resonances

We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at |t| ∼ 1 GeV, but the pQCD exchange dominance is deferred to |t| ∼ 3 GeV because of competing multiple soft rescattering effects. Base...

Crossing of two Coulomb–Blockade Resonances

We investigate theoretically the transport of non–interacting electrons through an Aharanov–Bohm (AB) interferometer with two quantum dots (QD) embedded into its arms. In the Coulomb–blockade regime, transport through each QD proceeds via a single resonance. The resonances are coupled through the arms of the AB device but may also be coupled directly. In the framework of the Landauer–Büttiker a...

ANCs and Radiation Widths of the First Two Resonances in

Asymptotic normalization coefficients (ANC), defining the normalization of the tail of nuclear bound-state wave functions projected onto the two-body channels, play an important role in nuclear reaction and structure theory. In our previous work, we have demonstrated that ANCs can be successfully used as normalization coefficients for the nonresonant capture amplitudes in the R matrix approach ...
