Two Micron‐Size Dark Dimensions

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Hadronic productions of a Higgs boson in association with two jets at next-to-leading order [PDF]

, 2010
We present the calculation of hadronic production of a Higgs boson in association with two jets at next-to-leading order in perturbation theory. We consider amplitudes in an effective theory in which the Higgs couples to gluons in the limit of a large ...

Tri-boson and WH production in the W + W + jj channel: predictions at full NLO accuracy and beyond

Journal of High Energy Physics
In this work, we present the first full NLO predictions for the process pp → μ + ν μ e+ ν ejj at the LHC in a typical tri-boson phase space. The NLO corrections reach 50% at the level of the fiducial cross section and have a very different hierarchy with

Two-loop mixed QCD-EW corrections to q q ¯ $$ q\overline{q} $$ → Hg, qg → Hq, and q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$

Journal of High Energy Physics, 2022
We compute the two-loop mixed QCD-Electroweak corrections to q q ¯ $$ q\overline{q} $$ → Hg and its crossed channels qg → Hq, q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$ , limiting ourselves to the contribution of light virtual quarks.

Simulation of a Three‐Nucleons System Transition on Quantum Circuits

Advanced Quantum Technologies, Volume 8, Issue 5, May 2025.
A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

Three-loop master integrals for the Higgs boson self-energy with internal top-quarks and W-bosons

Journal of High Energy Physics, 2022
We consider the full set of master integrals with internal top-and W-propagators contributing to the three-loop Higgs self-energy diagrams of order O $$ \mathcal{O} $$ (α 2 α s ).

Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Master integrals for O $$ \mathcal{O} $$ (αα s ) corrections to H → ZZ *

Journal of High Energy Physics, 2022
We present analytic results for all the Feynman integrals relevant for O $$ \mathcal{O} $$ (αα s ) virtual corrections to H → ZZ * decay. We use the method of differential equations to solve the master integrals while keeping the full dependence on the ...

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Off-Shell Effects for Single Top-Quark Production Processes at Hadron Colliders [PDF]

, 2011
We present a calculation of s- and t-channel single top-quark production and decay at next-to-leading order in QCD for the Tevatron and for the LHC. The calculation includes the off-shell effects of the intermediate top-quark and the non-factorisable ...
