Boundary Bound State Effects in Quantum Wires

We investigate the impact of boundary bound states on the dynamics of quantum fields, which propagate on star graphs modeling quantum wires. These states are localized in the vertex of the graph and decay exponentially in the bulk. We demonstrate that their contribution is completely fixed by causality (local commutativity), which represents a key point of our investigation. The boundary bound ...

Bound-state Effects in T ---) 7 + Resonance R - M

We study the effect of b-6 bound state dynamics on the amplitude for the reaction 7’ + 7 + Resonance. We argue from our results that the recently disci>vered ~(8320) must have a scalar, rather than a pseudoscalar, coupling to the b quark.

Bound-state effects on gluino-pair production at hadron colliders

We study bound-state effects on the pair production of gluinos at hadron colliders, in a context of the minimal supersymmetric extension of the standard model. Due to the expected large mass and the octet color-charge of gluinos, the bound-state effects can be substantial at the LHC. We find significant deformation of the invariant-mass distributions of a gluino-pair near the mass threshold, as...

Bound State Problem Solution

Second bound state of PsH.

The existence of a second bound state of PsH that is electronically stable and also stable against positron annihilation by the normal 2gamma and 3gamma processes is demonstrated by explicit calculation. The state can be found in the ;{2,4}S;{o} symmetries with the two electrons in a spin-triplet state. The binding energy against dissociation into the H(2p)+Ps(2p) channel was 7.03 x 10;(-4) har...
