Extracting Kinetic Freeze‐Out Properties in High‐Energy Collisions Using a Multisource Thermal Model
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.We study the transverse momentum (pT) spectra of neutral pions and identified charged hadrons produced in proton–proton (pp), deuteron–gold (d–Au), and gold–gold (Au–Au) collisions at the center of mass energy sNN=200 GeV. The study is made in the framework of a multisource thermal model used in the partonic level.

Hadronic productions of a Higgs boson in association with two jets at next-to-leading order [PDF]
, 2010 We present the calculation of hadronic production of a Higgs boson in association with two jets at next-to-leading order in perturbation theory. We consider amplitudes in an effective theory in which the Higgs couples to gluons in the limit of a large ...

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

Collinear spin correlations of final-state radiation in dense QCD matter [PDF]
Journal of High Energy PhysicsSpin correlations are required to reproduce the correct azimuthal dependence of matrix elements for successive branchings at disparate angles in QCD jets.

Schwinger-Dyson equations in QED and QCD the calculation of fermion-antifermion condensates [PDF]
, 2007 We present non-perturbative solutions for the fermion and boson propagators of QED in both three- and four-dimensions, and QCD. In doing so, we solve the coupled system of Schwinger-Dyson equations numerically in Euclidean space, investigating ...

Balance Function in High-Energy Collisions
Advances in High Energy Physics, 2015 Aspects and implications of the balance functions (BF) in high-energy physics are reviewed. The various calculations and measurements depending on different quantities, for example, system size, collisions centrality, and beam energy, are discussed ...

Probing transverse momentum broadening in heavy ion collisions
Physics Letters B, 2016 We study the dijet azimuthal de-correlation in relativistic heavy ion collisions as an important probe of the transverse momentum broadening effects of a high energy jet traversing the quark–gluon plasma.

Measurement of medium-induced acoplanarity in central Au-Au and pp collisions at $\sqrt{s_{\rm NN}}=200$ GeV using direct-photon+jet and $\pi^{0}$+jet correlations [PDF]
The STAR Collaboration reports measurements of acoplanarity using semi--inclusive distributions of charged--particle jets recoiling from direct photon and $\pi^{0}$ triggers, in central Au+Au and $pp$ collisions at $\sqrt{s_\mathrm{NN}}=200$ GeV ...

Experimental measurement of medium response and hard-soft correlation [PDF]
EPJ Web of ConferencesThe observation of jet energy loss, or 'quenching', as a result of jet-medium interactions has long been held as a fundamental signature of the hot- and-dense state of matter known as the quark-gluon plasma (QGP).

Infrared singularities in multi-leg scattering amplitudes [PDF]
, 2014 I discuss the state-of-the-art knowledge of long-distance singularities in multi-leg gauge-theory scattering amplitudes and report on an on-going calculation of the three-loop soft anomalous dimension through the renormalization of correlators of semi ...
