Polarization Effects In Hadron-Hadron Scatterings

open access: yesCumhuriyet Science Journal, 2018
In the case of diffraction scattering of hadrons by hadrons, a nonzeropolarization of the scattered particles arises, which is related to thelogarithmic derivative of the differential scattering cross section.Polarization changes sign in those reactions ...

Reggeization of the quark-quark scattering amplitude in QCD [PDF]

open access: yesPhysical Review D, 1996
$s$-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 ...

Measurement of the Top Quark Mass in the Dilepton Final State using the Matrix Element Method [PDF]

open access: yes, 2008
The top quark, discovered in 1995 by the CDF and D0 experiments at the Fermilab Tevatron Collider, is the heaviest known fundamental particle. The precise knowledge of its mass yields important constraints on the mass of the yet-unobserved Higgs boson ...

Flavor physics in the quark sector [PDF]

open access: yes, 2008
In the past decade, one of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor. In this time frame, measurements and the theoretical interpretation of their results have advanced tremendously. A

Jet shape and redistribution of the lost energy from jets in Pb + Pb collisions at the LHC in a multiphase transport model

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Jet-medium interaction involves two important effects: jet energy loss and medium response. The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions.

The colour of quarks [PDF]

open access: yesPhysics Letters B, 1996
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.

A Novel Multi-Gene Detection Platform for the Analysis of miRNA Expression

open access: yesScientific Reports, 2018
The study of miRNAs and their roles as non-invasive biomarkers has been intensely conducted in cancer diseases over the past decade. Various platforms, ranging from conventional qPCRs to Next Generation Sequencers (NGS), have been widely used to analyze ...

Covariant and heavy quark symmetric quark models [PDF]

open access: yesPhysical Review D, 1994
There exist relativistic quark models (potential or MIT-bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. Covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions.Proton form factor and M1 transitions in quarkonia are ...

Probing the composition of sub-millisecond rotating compact stars by r-modes instability

open access: yes, 2012
We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...
