Glueballs and hybrids are predicted to exist but searches for them have failed to provide conclusive evidence. One–gluon exchange is not an important part of strong interactions in this energy regime. Instead, quarks seem to interact indirectly, via changes of the QCD vacuum. Strong interactions seem to be governed by instanton–induced interactions; the chiral soliton model gives a more suitabl...

New results pertaining to colored static black hole solutions to the EinsteinYang-Mills equations are obtained. The isolated horizons framework is used to define the concept of Hamiltonian Horizon Mass of the black hole. An unexpected relation between the ADM and Horizon masses of the black hole solution and the ADM mass of the corresponding Bartnik-McKinnon soliton is found. These results can ...

We emphasize the importance of identifying non-exotic SUfl(3) partners of the Θ pentaquark, and indicate possible ways how to do it. We also use the soliton picture of baryons to relate Reggeon couplings of various baryons. These relations are used to estimate the Θ production cross section in high energy processes. We show that the corresponding cross sections are significantly suppressed rela...

The induced pseudotensor constant (weak electricity) of the nucleon is calculated in the framework of the chiral quark soliton model. This quantity originates from the G–parity violation and hence is proportional to mu−md. We obtain for mu −md = −5 MeV a value of gT /gA = −0.0038.

The term of multitime soliton has recently been coined in our research school to describe a multitime pulselike nonlinear wave (multitime solitary wave) which emerges from a collision with a similar pulse having unchanged shape and speed vector. To introduce this notion, it was necessary to introduce multitime PDEs that extend solitonic single-time PDEs via geometrical ingredients. This paper c...

We have studied theoretically the flow of superfluid 3 He-A in parallel-plate geometry. The equilibrium order-parameter texture is calculated numerically in two spatial dimensions consisting of the coordinates along the flow direction and perpendicular to the plates. The calculations have been done using the hydrostatic theory in the Ginzburg-Landau region and assuming a large external magnetic...

In this note, using Calabi’s method, we construct rotationally symmetric KählerRicci solitons on the total space of direct sum of fixed hermitian line bundle and its projective compactification, where the curvature of hermitian line bundle is Kähler-Einstein. These examples generalize the construction of Koiso, Cao and Feldman-Ilmanen-Knopf. 1 A little motivation In [1], the authors constructed...

Igor Klebanov * Department of Physics Joseph Henry Laboratories Princeton University Princeton, N J 08544 These lectures review the fundamentals of the Skyrme model of baryons and its relationship with the non-relativistic quark model and the large-N QCD. Special emphasis is placed on the problems the model experiences in perturbative treatment of SU(3) breaking. It is argued that the strange q...

In this article, the Enhanced ( / )-expansion method has been projected to find the traveling wave solutions for nonlinear evolution equations(NLEEs) via the (2+1)-dimensional Burgers equation. The efficiency of this method for finding these exact solutions has been demonstrated with the help of symbolic computation software Maple. By this method we have obtained many new types of complexiton s...

B List has recently studied a geometric flow whose fixed points correspond to static Ricci flat spacetimes. It is now known that this flow is in fact Ricci flow modulo pullback by a certain diffeomorphism. We use this observation to associate to each static Ricci flat spacetime a local Ricci soliton in one higher dimension. As well, solutions of Euclidean-signature Einstein gravity coupled to a...
