Using the QCD sum rule approach we study the Y(4140) state assuming that it can be described by a D* sD* s molecular state with JPC = 0++ quantum numbers. We evaluate the decay width into the channel Y J/ψΦ and we find the ...

A search for exotic resonances is performed, with a new particle decaying to a pair of vector bosons VZ, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays to dielectrons or dimuons. The ...

Old fields often become dominated by exotic plants establishing persistent community states. Ecosystem function in such novel plant assemblages may differ widely from that in the alternative, native-dominated counterparts. ...

Secondary succession may lead to novel, exotic-dominated community states differing in structure and function from the original native counterparts. We hypothesized that grassland soil processes associated with C and N ...
