Next-to-leading-logarithm kT resummation for Bc → J/ψ decays
Physics Letters B, 2020 We derive the kT resummation for a transverse-momentum-dependent charmonium wave function, which involves the bottom quark mass mb, the charm quark mass mc, and the charm quark transverse momentum kT, up to the next-to-leading-logarithm (NLL) accuracy ...

Effects of threshold resummation
, 1999 We investigate effects of threshold resummation of logarithmic corrections $\ln N$ in Mellin space quantitatively. Threshold resummation leads to enhancement of next-to-leading-order QCD predictions for jet production at large jet transverse energy ...

Threshold Resummation for the Inclusive-Hadron Cross-Section in pp Collisions [PDF]
, 2005 We study the resummation of large logarithmic perturbative corrections to the partonic cross sections relevant for the process pp->h X at high transverse momentum of the hadron h.

Leading Logarithm Quantum Gravity
UniverseThe continual production of long wavelength gravitons during primordial inflation endows graviton loop corrections with secular growth factors. During a prolonged period of inflation, these factors eventually overwhelm the small loop-counting parameter ...

Joint two-dimensional resummation in q T and 0-jettiness at NNLL
Journal of High Energy Physics, 2019 We consider Drell-Yan production pp → Z/γ ∗ → ℓ + ℓ − with the simultaneous measurement of the Z-boson transverse momentum q T and 0-jettiness T 0 $$ {\mathcal{T}}_0 $$ .

Uncovering Hidden Patterns: Approximate Resurgent Resummation from Truncated Series
MathematicsWe analyze truncated series generated as divergent formal solutions of non-linear ordinary differential equations. Motivating the study is a specific non-linear, first-order differential equation, which is the basis of the resurgent formulation of ...

Resummed Results for Hadron Collider Observables
EPJ Web of Conferences, 2016 Event shapes are invaluable QCD tools for theoretical calculations and experimental measurements. We revise the definition of these observables in e+e− annihilation and in hadron collisions, and give a review of the state-of-the-art results for their ...

On the Resummation of the $\alpha \ln^2 z Terms for QED Corrections to Deep-Inelastic $ep$ Scattering and $e^+e^-$ Annihilation [PDF]
, 1996 The resummation of the $\alpha \ln^2(z)$ non-singlet contributions is performed for initial state QED corrections. As examples, the effect of the resummation on neutral-current deep-inelastic scattering and the $e^+ e^- \rightarrow \mu^+ \mu ...

Analysis of the 3d massive renormalization group perturbative expansions: a delicate case
Condensed Matter Physics, 2010 The effectiveness of the perturbative renormalization group approach at fixed space dimension d in the theory of critical phenomena is analyzed. Three models are considered: the O(N) model, the cubic model and the antiferromagnetic model defined on the ...

Associated production of a top quark pair with a heavy electroweak gauge boson at NLO+NNLL accuracy
European Physical Journal C: Particles and Fields, 2019 We perform threshold resummation of soft gluon corrections to the total cross sections and the invariant mass distributions for production of a top-antitop quark pair associated with a heavy electroweak boson $$V = W^+$$ V=W+ , $$W^-$$ W- or Z in pp ...
