Several Effects Unexplained by QCD

open access: yesUniverse, 2018
Several new experimental discoveries in high energy proton interactions, yet unexplained by QCD, are discussed in the paper. The increase of the cross sections with increasing energy from ISR to LHC, the correlation between it and the behavior of the ...

Thermoelectric properties of the (an-)isotropic QGP in magnetic fields

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The Seebeck effect and the Nernst effect, which reflect the appearance of electric fields along x-axis and along y-axis ( $$E_{x}$$ E x and $$E_{y}$$ E y ), respectively, induced by the thermal gradient along x-axis, are studied in the QGP at an external

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 ...

Search for top quark decays t → qH with H → γγ using the ATLAS detector [PDF]

open access: yes, 2014
A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons.

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 Quarks of Attention

open access: yesCoRR, 2022
Attention plays a fundamental role in both natural and artificial intelligence systems. In deep learning, attention-based neural architectures, such as transformer architectures, are widely used to tackle problems in natural language processing and beyond.

A search for flavour changing neutral currents in top-quark decays in pp collision data collected with the ATLAS detector at s√=7TeV [PDF]

open access: yes, 2012
A search for flavour changing neutral current (FCNC) processes in top-quark decays by the ATLAS Collaboration is presented. Data collected from pp collisions at the LHC at a centre-of-mass energy of s√=7TeV during 2011, corresponding to an integrated ...
