Power suppressed corrections show new features of infrared cancellations
Paolo Ciafaloni, Denis Comelli, Alfredo Urbano
The cancellation of infrared (IR) divergences is an old topic in quantum field theory whose main results are condensed into the celebrated Kinoshita-Lee-Nauenberg (KLN) theorem. In…
On amplitudes, resonances and the ultraviolet completion of gravity
Rodrigo Alonso, Alfredo Urbano
This letter constructs, making use of the on-shell spinor-helicity formalism, a possible ultraviolet completion of gravity following a "bottom-up" approach. The assumptions of loca…
Charged neutron stars and observational tests of a dark force weaker than gravity
Marco Fabbrichesi, Alfredo Urbano
We discuss the possibility of exploring an unbroken U(1) gauge interaction in the dark sector by means of gravitational waves. Dark sector states charged under the dark force can g…
Clockwork/Linear Dilaton: Structure and phenomenology
Riccardo Torre
I briefly discuss the main phenomenological features and constraints of the Clockwork/Linear Dilaton (CW/LD) 5D geometry. This contribution is based on the work of ref. arXiv:1711.…
Dark Matter in the Standard Model?
Christian Gross, Antonello Polosa, Alessandro Strumia +2
We critically reexamine two possible Dark Matter candidate within the Standard Model. First, we consider the exa-quark. Its QCD binding energy could be large enough to mak…
New Physics in the Rayleigh-Jeans Tail of the CMB
Maxim Pospelov, Josef Pradler, Joshua T. Ruderman +1
We show that despite stringent constraints on the shape of the main part of the CMB spectrum, there is considerable room for its modification within its Rayleigh-Jeans (RJ) end, $ω…
