Repurposing lattice QCD results for composite phenomenology [PDF]
Physical Review D, 2019 A number of proposed extensions of the Standard Model include new strongly interacting dynamics, in the form of SU(N) gauge fields coupled to various numbers of fermions.

Next-to-leading-power kinematic corrections to DVCS: a scalar target
Journal of High Energy Physics, 2023 Using the recent results on the contributions of descendants of the leading twist operators to the operator product expansion of two electromagnetic currents we derive explicit expressions for the kinematic finite-t and target mass corrections to the ...

Process-Independent Effective Coupling: From QCD Green’s Functions to Phenomenology [PDF]
Few-body systems, 2018 This article reports on a very recent proposal for a new type of process-independent QCD effective charge (Binosi et al. in Phys Rev D 96(5):054026, 2017.

The photon energy spectrum in B → X s γ at N3LL′
Journal of High Energy Physics, 2023 We present predictions for the photon energy spectrum in inclusive B → X s γ decays mediated by the electromagnetic penguin operator O 7 to N3LL′. We use soft-collinear effective theory (SCET) to resum the singular contributions in the peak region at ...

Introductory lectures to large-N QCD phenomenology and lattice results [PDF]
, 2013 An elementary, pedagogical introduction to the large-N limit of QCD and to its phenomenological implications is presented, and a survey of lattice results in the ’t Hooft limit is briefly discussed.

Degrees of freedom and the phase transitions of two flavor QCD
, 2008 We study two effective models for QCD, the Nambu-Jona-Lasinio -model and the linear sigma model extended by including a Polyakov loop potential, which is fitted to reproduce pure gauge theory thermodynamics, and a coupling between the chiral fields and ...

The LHC Phenomenology of Vectorlike Confinement
, 2010 We investigate in detail the LHC phenomenology of "vectorlike confinement", where the Standard Model is augmented by a new confining gauge interaction and new light fermions that carry vectorlike charges under both the Standard Model and the new gauge ...

Isotensor Axial Polarizability and Lattice QCD Input for Nuclear Double-β Decay Phenomenology. [PDF]
Physical Review Letters, 2017 The potential importance of short-distance nuclear effects in double-β decay is assessed using a lattice QCD calculation of the nn→pp transition and effective field theory methods.

Journal of High Energy PhysicsWe investigate the inclusive production of double quarkonia (J/ψ, ψ(2S), Υ mesons) in polarized hadron-hadron collisions, considering the kinematic configuration where the transverse momentum of each pair of bound states is much smaller than its ...

Kinked tracks from Σ + baryons as a probe of light quark polarizations
Journal of High Energy Physics, 2023 Jets initiated by energetic quarks carry in an obvious way approximate information about the original quark energy and momentum. In a less obvious way, they also carry information about the quark polarization.
