Holographic description of the QCD phase diagram and out of equilibrium dynamics
, 2014 Holography provides a powerful tool to model QCD and other strongly coupled gauge dynamics. As examples of its power to compute in novel environments I review some recent results: these include models of the phase structure of QCD at finite temperature ...

Journal of High Energy PhysicsWe calculate the electromagnetic multipole moments of the Σ-type strange hidden-charm pentaquarks P ψs Σ $$ {P}_{\psi s}^{\Sigma} $$ — which form an isospin triplet with three distinct charge states (Σ+, Σ0, Σ−) offering independently measurable ...

A new analytic approach to physical observables in QCD [PDF]
, 2002 An analytic ghost-free model for the QCD running coupling a(Q(^2)) is proposed. It is constructed from a more general approach we developed particularly for investigating physical observables of the type F(Q(^2)) in regions that are inaccessible to ...

Electromagnetic tomography of spin- 3 2 $$ \frac{3}{2} $$ hidden-charm strange pentaquarks
Journal of High Energy PhysicsUnderstanding how quarks are spatially arranged inside exotic pentaquarks remains one of the key open problems in contemporary hadron spectroscopy. The electromagnetic multipole moments of hadrons provide a direct probe of their internal quark-gluon ...

Journal of High Energy PhysicsWe discuss the exclusive photoproduction of π + π − pairs in photon-proton and in proton-proton collisions at high energies. The ρ 0, ω, f 2(1270), and non-resonant (Drell-Söding) contributions are considered.

Twisted mass QCD at finite temperature [PDF]
, 2012 We discuss the use of Wilson fermions with twisted mass for simulations of QCD thermodynamics. As a prerequisite for a future analysis of the finite-temperature transition making use of automatic O(a) improvement, we investigate the phase structure in ...

Predicting isovector charmonium-like states from X(3872) properties
Journal of High Energy PhysicsUsing chiral effective field theory, we predict that there must be isovector charmonium-like D D ¯ ∗ $$ D{\overline{D}}^{\ast } $$ hadronic molecules with J PC = 1++ denoted as W c1.

Short-range production of three bottom mesons
Journal of High Energy PhysicsPrevious investigations of the three-body dynamics of B mesons have shown that no Efimov effect arises in systems composed of three B and B * mesons.

Superselection rules, quantum error correction, and quantum chromodynamics
Journal of High Energy PhysicsWe investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction.
