This paper is a review of the present status neutrino mass physics, which grew out an APS sponsored study neutrinos in 2004. After discussion knowledge masses and mixing some popular ways to probe new physics implied by recent data, it summarizes what can be learned about interactions as well nature beyond Standard Model from various proposed experiments. The intriguing possibility that may at heart our understanding long standing puzzle cosmology, i.e. origin matter–antimatter asymmetry...
This chapter of the report "Flavor in era LHC" Workshop discusses theoretical, phenomenological and experimental issues related to flavor phenomena charged lepton sector conserving CP-violating processes. We review current limits main theoretical models for structure fundamental particles. analyze consequences available data, setting constraints on explicit beyond standard model, presenting benchmarks discovery potential forthcoming measurements both at LHC low energy, exploring options...
We perform a state-of-the-art global fit to all Higgs data. synthesise them into 'universal' form, which allows easily test any desired model. apply the proposed methodology extract from data branching ratios, production cross sections, couplings and analyse composite models, models with extra doublets, supersymmetry, particles in loops, anomalous top couplings, invisible decays Dark Matter. Best regions lie around Standard Model predictions are well approximated by our fit. Latest exclude...
The measurements of the Higgs boson and top quark masses can be used to extrapolate Standard Model potential at energies up Planck scale. Adopting a NNLO renormalization procedure, we: i) find that electroweak vacuum stability is present allowed, discuss associated theoretical experimental errors prospects for its future tests; ii) determine boundary conditions allowing existence shallow false minimum slightly below scale, which stable configuration might have been relevant primordial...
The relation between leptogenesis and CP violation at low energies is analyzed in detail the framework of minimal seesaw mechanism. Working, without loss generality, a weak basis where both charged lepton right-handed Majorana mass matrices are diagonal real, we consider convenient generic parametrization Dirac neutrino Yukawa coupling matrix identify necessary condition which has to be satisfied order establish direct link energies. In context LMA solution solar problem, present scenarios...

Our peculiar velocity with respect to the CMB rest frame is known induce a large dipole in CMB. However, motion of an observer has also effect distorting anisotropies at all scales, as shown by Challinor and Van Leeuwen (2002), due aberration Doppler effects. We propose measure independently our local using off-diagonal two-point correlation functions for high multipoles. study observability signal temperature polarization anisotropies. point out that Planck can $\beta$ error about 30%...
In this chapter we give a pedagogical introduction to effective potential methods in field theories. We first review the general functional leading concept of action and potential. Focusing on compute radiative contributions, starting from original 1973 seminal paper by Sidney Coleman Erick Weinberg one-loop corrections, along with its improvement renormalization group equations, as well some basic results thermal theory, including corrections concentrate physical applications potential: i)...
A bstract The recent results that θ 13 is relatively large, of the order previous upper bound, and indications a sizable deviation 23 from maximal value are in agreement with predictions Anarchy lepton sector. quark charged hierarchies can then be reproduced SU(5) GUT context by attributing non-vanishing U(1) FN charges, different for each family, only to tenplet states. fact observed mass stronger up quarks than down leptons supports this idea. As discussed past, flexible ⊗ , patterns...
In this paper we have considered the possibility that Standard Model, and its minimal extension with addition of singlets, merges a high-scale supersymmetric theory at scale satisfying Veltman condition therefore no sensitivity to cutoff. The matching Model is achieved Planckian scales. complex singlet depends on strength coupling between Higgs fields. For order one values coupling, still in perturbative region, can be located TeV ballpark. Even absence quadratic divergences there remains...
If the standard model is valid up to very high energies it known that Higgs potential can develop a local minimum at field values around ${10}^{15}--{10}^{17}\text{ }\text{ }\mathrm{GeV}$, for narrow band of top quark and masses. We show in scalar-tensor theory gravity such false vacuum give rise viable inflation if barrier shallow, allowing tunneling relaxation into electroweak scale true vacuum. The amplitude cosmological density perturbations from directly linked value minimum. Requiring...
For a narrow band of values the top quark and Higgs boson masses, standard model potential develops false minimum at energies about 10(16) GeV, where primordial inflation could have started in cold metastable state. A graceful exit to radiation-dominated era is provided, e.g., by scalar-tensor gravity models. We pointed out that if happened this minimum, mass has be range 126.0±3.5 ATLAS CMS subsequently reported excesses events. Here we show for these mass, inflationary gravitational wave...
We study the gauge-independent observables associated with two interesting stationary configurations of Standard Model Higgs potential (extrapolated to high energy according present state art, namely next-to-next-to-leading order): i) value top mass ensuring stability SM electroweak minimum and ii) at a rising inflection point. examine in detail reappraise experimental theoretical uncertainties which plague their determination, finding that is compatible data $1.5\ensuremath{\sigma}$ level...
It has recently been shown that the quantum Boltzmann equations may be relevant for leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depends upon previous dynamics of system. This memory effect in is particularly important resonant where generated by decays nearly mass-degenerate right-handed neutrinos. We study impact non-trivial time evolution so-called minimal lepton flavour violation framework charged-lepton and neutrino Yukawa couplings are only...
