Mean field approximation for effective theories of lattice QCD [PDF]

open access: yesProceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2023
For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime. In practice, the evaluation of these theories is complicated by the appearance of long-range and multipoint interaction terms.

Unraveling the Structure of Hadrons with Effective Field Theories of QCD [PDF]

open access: yes, 2004
Effective Field theory is a powerful framework based on controlled expansions for problems with a natural separation of energy scales. This technique is particularly important for QCD, the theory of strong interactions, due to the vast diversity of phenomena that it describes.

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics [PDF]

open access: yes, 2022
Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...

Effective field theory for warm QCD [PDF]

open access: yesPhysical Review D, 2018
Using only global symmetries of QCD, we set up an effective model of quarks at finite temperature near the cross over, including all possible terms up to dimension 6. We first treat this in mean field theory. Then we investigate low-energy fluctuations around it up to one-loop order in fermions below the cross over.

Logarithmic corrections in Symanzik’s effective theory of lattice QCD [PDF]

open access: yes, 2021
Einer der finalen Schritte in Simulationen von Gitter Quantenchromodynamik (QCD) oder Gittereichtheorie ist die Kontinuumsextrapolation, um die eigentliche Kontinuumsphysik zu extrahieren.

Amplitude’s positivity vs. subluminality: causality and unitarity constraints on dimension 6 & 8 gluonic operators in the SMEFT

open access: yesJournal of High Energy Physics, 2023
We derive the causality and unitarity constraints on dimension 6 and dimension 8 Gluon field strength operators in the Standard Model Effective Field Theory (SMEFT). In the first part of the paper, we use the ‘amplitude analysis’ i.e. dispersion relation

Resummation and renormalization of kinematical effects in inclusive P-wave quarkonium production

open access: yesJournal of High Energy Physics, 2023
We investigate the renormalization properties of the shape function formalism for inclusive production of P-wave heavy quarkonia, which arises from resumming a class of corrections coming from kinematical effects associated with the motion of the heavy ...

Resolution of the LHCb η c anomaly

open access: yesJournal of High Energy Physics, 2023
Due to the heavy-quark symmetry of Non-Relativistic Quantum Chromodynamics (NRQCD), the cross-section for the production of η c can be predicted. This NRQCD prediction when confronted with data from the LHCb is seen to fail miserably.

Inclusive J/ψ photoproduction at the ILC within the framework of non-relativistic QCD

open access: yesJournal of High Energy Physics, 2022
Based on the non-relativistic quantum chromodynamics factorization framework, we study the inclusive J/ψ photoproduction at the future high energy e + e − collider, International Linear Collider(ILC), where the initial photons come from the back ...
