Discovery and Exclusion Prospects for Staus Produced by Heavy Higgs Boson Decays at the LHC
In a previous work, we developed a search strategy for staus produced by the decay of the heavy CP‐even Higgs boson H within the context of the large tanβ regime of the minimal supersymmetric standard model (MSSM) in a scenario of large stau mixing. Here, we study the performance of such search strategy by confronting it with the complementary mixing ...

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays
The QCD×QED factorization is studied for two-body non-leptonic and semi-leptonic B decays with heavy-light final states. These non-leptonic decays, like B ¯ s 0 → D s + π − $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{+}{\pi}^{-} $$ and B ¯ d 0 → D + K − $$ {\

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties. We obtain new experimental limits on the scale of compositeness, the mixing with singlets and doublets with the

A formalism for the resummation of non-factorizable observables in SCET
In the framework of soft-collinear effective theory (SCET), we show how to formulate the resummation for a broad family of final-state, global observables in high-energy collisions in a general way that is suitable for a numerical calculation.

Charting the coming synergy between lattice QCD and high-energy phenomenology [PDF]
Building upon the PDFSense framework developed in Ref. [1], we perform a comprehensive analysis of the sensitivity of present and future high-energy data to a number of quantities commonly evaluated in lattice gauge theory, with a particular focus on the

On the Interpretation of Nonresonant Phenomena at Colliders
With null results in resonance searches at the LHC, the physics potential focus is now shifting towards the interpretation of nonresonant phenomena. An example of such shift is the increased popularity of the EFT programme. We can embark on such programme owing to the good integrated luminosity and an excellent understanding of the detectors, which ...

Process-Independent Effective Coupling: From QCD Green’s Functions to Phenomenology [PDF]

QCD Effective Locality: A Theoretical and Phenomenological Review [PDF]
About ten years ago, the use of standard functional manipulations was demonstrated to imply an unexpected property satisfied by the fermionic Green’s functions of QCD and dubbed Effective Locality. This feature of QCD is non-perturbative, as it results from a full gauge invariant integration of the gluonic degrees of freedom.

Study of Bs⟶ϕℓ+ℓ− Decays in the PQCD Factorization Approach with Lattice QCD Input
In this paper, we studied systematically the semileptonic decays Bs⟶ϕl+l− with l− = (e−, μ−, τ−) by using the perturbative QCD (PQCD) and the “PQCD+Lattice” factorization approach, respectively. We first evaluated all relevant form factors Fi(q2) in the low‐q2 region using the PQCD approach, and we also took the available lattice QCD results at the ...
