We show that the signature of two boosted $W$-jets plus large missing energy is very promising to probe heavy charged resonances ($X^\pm$) through process $pp\to X^+X^-\to W^+W^- X^0 X^0$ where $X^0$ denotes dark matter candidate. The hadronic decay mode $W$ boson considered maximize number signal events. When mass split between $X^\pm$ and large, one has utilize jet-substructure technique anal...

The main source of jets at HERA a comes from collisions between protons and quasi-real photons (Q ≈ 0, where Q is the virtuality of the photon) emitted by the electron beam (photoproduction). At lowest order QCD, two hard scattering processes contribute to jet production : the resolved process, in which a parton from the photon interacts with a parton from the proton, producing two jets in the ...
