Search for Signatures of New Heavy Top Quark of the Fourth
... In this work, we searched for the existence of the new heavy quark top t ′ fourth generation quark in the charged trilepton e + , e − , µ plus jets and missing transverse momentum decay channel. In this channel, the t ′ quarks are produced in pairs tt ′ and the final state contains three leptons tha ...

... Gravity, acting between massive objects, cannot yet be incorporated consistently in this quantum field theoretical picture and this defines one of the major unsolved theoretical problems. Gravitons, believed to mediate gravitational interactions as gauge bosons, exhibit two units of spin; this under ...
