“…The above results are in line with the expected form of the B 2 coefficients (see eq. (2.3)) and hence consistent with previous observations in the literature [81] that B 2 is always related to the endpoint terms of the DGLAP splitting 4 Specifically we can see from eq. (2.1) the presence of a term B1αs(q 2 ) which, with the transverse momentum q 2 ∝ θ 2 g , results in the presence of a term of the form 3/2 α 2 s b0 ln θ 2 g as seen in our results after z integration.…”

“…QCD has long been confirmed as the theory of strong interactions and is now decisively in the precision era. The demand for percent-level precision on QCD calculations is primarily being driven by LHC phenomenology with the large volume of experimental data accumulated at the LHC and the focus on firmly establishing the properties of the Standard Model Higgs sector as well as the search for possible subtle signs of new physics [1][2][3][4].…”

We explore the collinear limit of final-state quark splittings at order $$ {\alpha}_s^2 $$ α s 2 . While at general NLL level, this limit is described simply by a product of leading-order 1 → 2 DGLAP splitting functions, at the NNLL level we need to consider 1 → 3 splitting functions. Here, by performing suitable integrals of the triple-collinear splitting functions, we demonstrate how one may extract $$ {\mathrm{\mathcal{B}}}_2^q(z) $$ ℬ 2 q z , a differential version of the coefficient $$ {\mathrm{\mathcal{B}}}_2^q $$ ℬ 2 q that enters the quark form factor at NNLL and governs the intensity of collinear radiation from a quark. The variable z corresponds to the quark energy fraction after an initial 1 → 2 splitting, and our results yield effective higher-order splitting functions, which may be considered as a step towards the construction of NNLL parton showers. Further, while in the limit z → 1 we recover the standard soft limit results involving the CMW coupling with scale kt, the z dependence we obtain also motivates the extension of the notion of a physical coupling beyond the soft limit.

A new measurement of the muon anomalous magnetic moment, gμ− 2, has been reported by the Fermilab Muon g-2 collaboration and shows a 4.2 σ departure from the most precise and reliable calculation of this quantity in the Standard Model. Assuming that this discrepancy is due to new physics, we concentrate on a simple supersymmetric model that also provides a dark matter explanation in a previously unexplored region of supersymmetric parameter space. Such interesting region can realize a Bino-like dark matter candidate compatible with all current direct detection constraints for small to moderate values of the Higgsino mass parameter |μ|. This in turn would imply the existence of light additional Higgs bosons and Higgsino particles within reach of the high-luminosity LHC and future colliders. We provide benchmark scenarios that will be tested in the next generation of direct dark matter experiments and at the LHC.

“…The exclusions [16] translate into fairly weak current bounds for our models and we thus simply present the projected LHCb bounds obtained from Ref. [66,67] in the same spirit as for the di-muon channel.…”

Exploring new possibilities to discover a light pseudo-scalar at LHCb

We study the possibility of observing a light pseudo-scalar a at LHCb. We target the mass region $$2.5\,\mathrm{GeV}\lesssim m_a\lesssim 60\,\mathrm{GeV}$$ 2.5 GeV ≲ m a ≲ 60 GeV and various decay channels, some of which have never been considered before: muon pairs, tau pairs, D meson pairs, and di-photon. We interpret the results in the context of models of 4D Composite Higgs and Partial Compositeness in particular.
