A Monte Carlo global analysis of the Standard Model Effective Field Theory: the top quark sector [PDF]

open access: yesJournal of High Energy Physics, 2019
A bstractWe present a novel framework for carrying out global analyses of the Standard Model Effective Field Theory (SMEFT) at dimension-six: SMEFiT.

New Neutron Star Equation of State with Quark–Hadron Crossover [PDF]

open access: yesAstrophysical Journal, 2019
We present a much improved equation of state for neutron star matter, QHC19, with a smooth crossover from the hadronic regime at lower densities to the quark regime at higher densities. We now use the Togashi et al. equation of state, a generalization of

Signatures of Quark-Hadron Phase Transitions in General-Relativistic Neutron-Star Mergers. [PDF]

open access: yesPhysical Review Letters, 2018
Merging binaries of neutron-stars are not only strong sources of gravitational waves, but also have the potential of revealing states of matter at densities and temperatures not accessible in laboratories.

Quantum oscillons may be long-lived

open access: yesJournal of High Energy Physics, 2023
Hertzberg has constructed a quantum oscillon that decays into pairs of relativistic mesons with a power much greater than the radiation from classical oscillon decay.

QLBT: a linear Boltzmann transport model for heavy quarks in a quark-gluon plasma of quasi-particles

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We develop a new heavy quark transport model, QLBT, to simulate the dynamical propagation of heavy quarks inside the quark-gluon plasma (QGP) created in relativistic heavy-ion collisions.

Higgs Boson Pair Production in Gluon Fusion at Next-to-Leading Order with Full Top-Quark Mass Dependence. [PDF]

open access: yesPhysical Review Letters, 2016
We present the calculation of the cross section and invariant mass distribution for Higgs boson pair production in gluon fusion at next-to-leading order (NLO) in QCD. Top-quark masses are fully taken into account throughout the calculation.

Private Governance, Hegemonic Struggles, and Institutional Outcomes in the Transnational Cotton Commodity Chain

open access: yesJournal of World-Systems Research, 2015
Transnational firms have rolled out new forms of private governance at the same time as the rise of new economic powerhouses like China has fomented growing inter-state tensions.

Off-equilibrium non-Gaussian fluctuations near the QCD critical point: an effective field theory perspective

open access: yesJournal of High Energy Physics, 2022
The non-Gaussian fluctuations of baryon density are sensitive to the presence of the conjectured QCD critical point. Their observational consequences are crucial for the ongoing experimental search for this critical point through the beam energy scan ...

Parton Distribution Functions, $\alpha_s$ and Heavy-Quark Masses for LHC Run II [PDF]

open access: yes, 2017
We determine a new set of parton distribution functions (ABMP16), the strong coupling constant $\alpha_s$ and the quark masses $m_c$, $m_b$ and $m_t$ in a global fit to next-to-next-to-leading order (NNLO) in QCD. The analysis uses the $\overline{\mathrm{

Dark quark nuggets [PDF]

open access: yesPhysical Review D, 2018
"Dark quark nuggets", a lump of dark quark matter, can be produced in the early universe for a wide range of confining gauge theories and serve as a macroscopic dark matter candidate.
