Radiatively Induced Neutrino Masses and Large Higgs-Neutrino Couplings in the Standard Model with Majorana Fields

1999

The Higgs sector of the Standard Model with one right-handed neutrino per family is systematically analyzed. In a model with intergenerational independent mixings between families, we can account for very light neutrinos acquiring Majorana masses radiatively at the first electroweak loop level. We also find that in such a scenario the Higgs coupling to the light-heavy neutrinos and to the heavy-heavy ones may be remarkably enhanced with significant implications for the production of these heavy neutrinos at high energy colliders.

Top quark anomalous tensor couplings in the two-Higgs-doublet models

2013

We compute the one loop right and left anomalous tensor couplings (g(R) and g(L), respectively) for the top quark, in the aligned two-Higgs-doublet model. They are the magnetic-like couplings in the most general parameterization of the tbW vertex. We find that the aligned two-Higgs doublet model, that includes as particular cases some of the most studied extensions of the Higgs sector, introduces new electroweak contribution's and provides theoretical predictions that are very sensitive to both new scalar masses and the neutral scalar mixing angle. For a largo area in the parameters space we obtain significant deviations in both the real and the imaginary parts of the couplings gR and gL, c…

$m^{min}_{T}$ kinematic distribution in the signal regions showing the data and the post-fit background in sr3$\ell$. The fit uses all CR and SRs, and the distributions are shown inclusively in $m_{Z\ell}$. The full event selection for each of the corresponding regions is applied except for the variable shown, where the selection is indicated by a blue arrow. the first (last) bin includes underflow (overflow) events. The other category mostly consists of $tWZ$, $t\bar{t}W$, and $tZ$ processes. The hatched bands indicate the combined theoretical, experimental, and MC statistical uncertainties. The bottom panel shows the ratio between the data and the post-fit background prediction.

Normanowie, wikingowie a ich przedstawienia w świecie gier komputerowych (na wybranych przykładach)

2018

Pomimo ogromnego postępu w badaniach skandynawskich i normańskich, istnieje jeszcze pole we współczesnej popkulturze, które powiela pewne stare stereotypy. To rynek gier komputero-wych, który kwitnie od ponad czterdziestu lat. Dlatego w artykule przedstawiono to zjawisko chronologicznie – na wybranych przykładach od lat 80. do chwili obecnej. Uczyniono to na pod-stawie tytułów na komputery C, najczęściej strategii i gier R G (Role laying Games), ponieważ ta platforma jest jedną z najstarszych i pomimo szybkiego rozwoju konsol, wciąż im nie uległa. Niestety, nie istnieje literatury naukowa poświęcona wikingom i Normanom w grach wideo, więc do pewnego stopnia badania są pionierskie. Podczas g…

WCxf: An exchange format for Wilson coefficients beyond the Standard Model

2018

We define a data exchange format for numerical values of Wilson coefficients of local operators parameterising low-energy effects of physics beyond the Standard Model. The format facilitates interfacing model-specific Wilson coefficient calculators, renormalisation group (RG) runners, and observable calculators. It is designed to be unambiguous (defining a non-redundant set of operators with fixed normalisation in each basis), extensible (allowing the addition of new EFTs or bases by the user), and robust (being based on industry standard file formats with parsers implemented in many programming languages). We have implemented the format for the Standard Model EFT (SMEFT) and for the weak e…

Probing nonstandard neutrino-electron interactions with solar and reactor neutrinos

2009

Most neutrino mass extensions of the standard electroweak model entail non-standard interactions which, in the low energy limit, can be parametrized in term of effective four-fermion operators $\nu_\alpha \nu_\beta \bar f f $. Typically of sub-weak strength, $\epsilon_{\alpha \beta} G_F$, these are characterized by dimensionless coupling parameters, $\epsilon_{\alpha \beta}$, which may be relatively sizeable in a wide class of schemes. Here we focus on non-universal (NU) flavor conserving couplings ($\alpha = \beta$) with electrons ($f = e$) and analyse their impact on the phenomenology of solar neutrinos. We consistently take into account their effect both at the level of propagation where…
