Reggeization of the quark-quark scattering amplitude in QCD [PDF]
$s$-channel discontinuity of quark-quark scattering amplitude with gluon quantum numbers in the $t$ channel and negative signature is calculated in the Regge kinematical region in the two-loop approximation. Using this discontinuity and assuming that the Regge asymptotic behaviour is given by the Reggeized gluon contribution, we calculate the gluon ...

PARTICLE PHYSICS: PROBING THE FUNDAMENTAL CONSTITUENTS OF MATTER AND FORCES OF NATURE
This study investigates the fundamental constituents of matter—quarks, leptons, gauge bosons—and the interactions that govern them, through a rigorous mixed-methods analysis integrating quantitative collider data and theoretical synthesis.

Signals with six bottom quarks for charged and neutral Higgs bosons
In extensions of two Higgs doublet models with vectorlike quarks, the decays of vectorlike quarks may easily be dominated by cascade decays through charged or neutral Higgs bosons leading to signatures with 6 top or bottom quarks.

The fascinating search of the inner boundaries of the Universe, has been entangled, since the birth of greek philosophy 25 centuries ago, with the main epistemological changes in the History of Science.

The charged Higgs from the Bottom-Up: probing flavor at the LHC
We systematically study model-independent constraints on the three generic charged Higgs couplings to b-quarks and up-type quarks. While existing LHC searches have focussed on the tb coupling, we emphasize that the LHC plays a crucial role in probing ...

It is shown that colour can only be defined on gauge invariant states. Since the ability to associate colour with constituent quarks is an integral part of the constituent quark model, this means that, if we want to extract constituent quarks from QCD, we need to dress Lagrangian quarks with gluons so that the result is gauge invariant.

Proton internal pressure distribution suggests a simple proton structure
Understanding the origin of quark confinement in hadrons remains one of the most challenging problems in modern physics. Recently, the pressure distribution inside the proton was measured via deeply virtual Compton scattering.

Kinked tracks from Σ + baryons as a probe of light quark polarizations
Jets initiated by energetic quarks carry in an obvious way approximate information about the original quark energy and momentum. In a less obvious way, they also carry information about the quark polarization.
