Local analytic sector subtraction for initial- and final-state radiation at NLO in massless QCD
Gloria Bertolotti, Paolo Torrielli, Sandro Uccirati +1
Within the framework of local analytic sector subtraction, we present the subtraction of next-to-leading-order QCD singularities for processes featuring massless coloured particles…
Resummation effects in the bottom-quark fragmentation function
Fabio Maltoni, Giovanni Ridolfi, Maria Ubiali +1
We compute the perturbative component of the fragmentation function of the quark to the best of the present theoretical knowledge. The fixed-order calculation to order …
Improving methods and predictions at high-energy colliders within collinear factorisation
V. Bertone, M. Cacciari, S. Frixione +3
We illustrate how electron Parton Distribution Functions (PDFs) with next-to-leading collinear logarithmic accuracy must be employed in the context of perturbative predictions for…
Sensitivity to New Physics in final states with multiple gauge and Higgs bosons
Alessandra Cappati, Roberto Covarelli, Paolo Torrielli +1
We analyse the sensitivity to beyond-the-Standard-Model effects of hadron-collider processes involving the interaction of two electroweak and two Higgs bosons, VVHH, with V being e…
Initial state QED radiation aspects for future colliders
S. Frixione, E. Laenen, C. M. Carloni Calame +25
This white paper concerns theoretical and phenomenological aspects relevant to the physics of future colliders, in particular regarding initial-state QED radiation. The co…
