The HERMES experiment collected from 1995 to 2007 a wealth of deep-inelastic scattering data using 27.6 GeV longitudinally polarized electrons and positrons and various unpolarized as well as longitudinally and transversely polarized gas targets. This allowed for a series of diverse measurements. Among them are measurements that provide information on the three-dimensional structure of the...
We provide a universal expression of cross sections for the exclusive vector meson production and deeply virtual Compton scattering (DVCS) in photon-proton and photon-nucleus interactions based on the geometric scaling phenomenon. The theoretical parametrization based on the scaling property depends only on the single variable $\tau_A = \frac{Q^2}{Q_{sat}^2}$, where the saturation scale,...
We show that the effective field equations for a recently formulated
polynomial affine model of gravity,
in the sector of a torsion-free connection, accept general Einstein
manifolds—with or without cosmological
constant—as solutions. Moreover, the effective field equations are
partially those obtained from a gravitational
Yang–Mills theory known as Stephenson–Kilmister–Yang...
In the present work the set of stationary solutions of the Gross-Neveu model in t'Hooft limit is extended. Such extension is obtained striving a hidden supersymmetry associated to disconnected sets of stationary solutions. It is shown how the supersymmetry arises from the Darboux-Miura transformations between Lax pairs of stationary modified Korteweg-de Vries and the stationary Korteweg-de...
The Belle II experiment is a substantial upgrade of Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+e^-$ collider. The detector is in its final phase of construction and the accelerator has successfully completed the first phase of commissioning. The design luminosity of $8 \times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data,...
The Higgs boson discovered at the LHC has completed the standard model of particle physics. The LHC run2 with a center of mass energy of 13 TeV is now in progress, where properties of the Higgs boson and other particles are measured to be consistent with expectations of the standard model and no indication of new particles has been observed up to now. The International Linear Collider (ILC) is...
The Compact Linear Collider (CLIC) is a proposed
high-luminosity linear electron-positron collider at the energy
frontier. For optimal physics potential CLIC is foreseen to be built and
operated in a staged approach, with three centre-of-mass energy stages;
ranging from a few hundred GeV up to 3 TeV. The initial energy stage is
planned to operate just above the top-quark pair production...
We formulate a predictive model of fermion masses and mixing based on a $\Delta(27)$ family symmetry. In the quark sector the model leads to the viable mixing inspired texture where the Cabibbo angle comes from the down quark sector and the other angles come from the up quark sector. In the lepton sector the model generates a predictive structure for charged leptons and, after radiative...
Neutrinoless double beta decay ($0\nu\beta\beta$), being a lepton
number violating (LNV) process, offers an opportunity
to probe physics beyond the SM in a way complementary or maybe even unavailable for collider experiments. Its non-observation allows to
constrain LNV beyond standard model (BSM) physics. There are two different kind of
contributions to the $0\nu\beta\beta$ amplitude: the...
The evasive nature of Dark Matter (DM) has been challenging experimentalists and theorists alike for decades. In order to bridge both approaches, we investigate the phenomenology that two different simplified models would imprint on various experiments, stressing the importance of the complementarity that they offer. We start by analysing the dark sequential $Z'$ portal, where direct...
Leptoquarks occur in many new physics scenarios and could be the
next discovery at the LHC. In this talk we point out that
a model-independent search strategy covering all possible leptoquarks is
possible and has not yet been fully exploited. To be systematic we organize
the possible leptoquark final states according to a leptoquark matrix with
entries corresponding to nine experimentally...
