A geographical study of (M)over-bar(2)(P-2, 4)(main)

We discuss criteria for a stable map of genus two and degree 4 to the projective plane to be smoothable, as an application of our modular desingularisation of (M) over bar (2,n)(P-r, d)(main) via logarithmic geometry and Gorenstein singularities. ...

A bb(b)over-bar(b)over-bar di-bottomonium at the LHC?

Angelo Esposito

We study the case of a di-bottomonium bb (b) over bar(b) over bar particle at the LHC. Its mass and decay width are obtained within a new model of diquark-antidiquark interactions in tetraquarks. The same model solves several open problems on the phenomeno ...
