PPPC 4 DM: A Poor Particle Physicist Cookbook for Neutrinos from DM annihilations in the Sun

Pietro Baratella, Marco Cirelli, Andi Hektor +3

We provide ingredients and recipes for computing neutrino signals of TeV-scale Dark Matter annihilations in the Sun. For each annihilation channel and DM mass we present the energy…

A bound on the charm chromo-EDM and its implications

Filippo Sala

We derive bounds on the electric and chromo-electric dipole moments of the charm quark. The second one turns out to be particularly strong, and we quantify its impact on models tha…

Higgs couplings and electroweak observables: a comparison of precision tests

Riccardo Barbieri, Andrea Tesi

Is the weak scale natural? This ever pending question makes the search for new particle production a highly motivated primary goal of the next LHC phase. These searches may or may…

Towards Completing the Standard Model: Vacuum Stability, EWSB and Dark Matter

Emidio Gabrielli, Matti Heikinheimo, Kristjan Kannike +3

We study the standard model (SM) in its full perturbative validity range between and the Landau pole, assuming that a yet unknown gravitational theory in the UV do…

One or more Higgs bosons?

Riccardo Barbieri, Dario Buttazzo, Kristjan Kannike +2

Now that one has been found, the search for signs of more scalars is a primary task of current and future experiments. In the motivated hypothesis that the extra Higgs bosons of th…

Investigating the near-criticality of the Higgs boson

Dario Buttazzo, Giuseppe Degrassi, Pier Paolo Giardino +4

We extract from data the parameters of the Higgs potential, the top Yukawa coupling and the electroweak gauge couplings with full 2-loop NNLO precision, and we extrapolate the SM p…

Predicting the tau strange branching ratios and implications for V_{us}

Mario Antonelli, Vincenzo Cirigliano, Alberto Lusiani +1

Hadronic tau decays provide several ways to extract the Cabbibo-Kobashi-Maskawa (CKM) matrix element V_{us}. The most precise determination involves using inclusive tau decays and…

Exploring the Higgs sector of a most natural NMSSM

Riccardo Barbieri, Dario Buttazzo, Kristjan Kannike +2

The Next to Minimal Supersymmetric Standard Model (NMSSM) with a Higgs-singlet coupling λ close to unity, moderate tan β and stop masses below 1 TeV minimizes the fine tuning of th…

The universal Higgs fit

Pier Paolo Giardino, Kristjan Kannike, Isabella Masina +2

We perform a state-of-the-art global fit to all Higgs data. We synthesise them into a 'universal' form, which allows to easily test any desired model. We apply the proposed methodo…
