ALICE Collaboration

Heavy Ions

Talk

ALICE at the LHC was designed to study the properties of Quantum Chromodynamics (QCD) from pp to heavy-ion collisions. In this context, the measurement of the $\Sigma^{0}$ baryon could serve as an additional test of isospin symmetry, which predicts the ratio of the yields of $\Sigma^{0}$ and $\Lambda$ baryons to be 1/3 according to their isospin projections. In addition, exploring this ratio...

Dr Jianlong Lu (National University of Singapore)

Neutrino Physics

Poster

In the canonical Type-I seesaw with three heavy Majorana singlets, oscillation data fix the low-energy mass matrix $m_\nu$ but do not uniquely determine the heavy–light mixing. Using the exact relation $m_\nu=-R D_N R^T$, we show that the full $m_\nu$-preserving ambiguity is a right action $R\to RF$ with $F D_N F^T=D_N$, i.e. $\mathcal G=D_N^{1/2}O(3,\mathbb C)D_N^{-1/2}$. This organizes...

Carlos Vazquez Sierra (Universidade da Coruña (ES))

Quark and Lepton Flavor Physics

Talk

Processes mediated by the quark-level transition $b \to s \ell^+\ell^-$ are highly suppressed in the SM, as they occur only through higher-order electroweak loop diagrams. This suppression makes FCNC processes particularly sensitive to contributions from physics beyond the SM. They therefore provide an excellent laboratory to test Lepton Flavour Universality (LFU), a fundamental property of...

A major challenge for neutrino oscillation experiments, which rely on wide-band fluxes, is the accurate reconstruction of neutrino energy from observed final-state particles.

The planned upgrades to the Large Hadron Collider for the HL-LHC era will gradually increase the nominal luminosity, aiming for peak values close to 5×10$^{34}$ cm$^{-2}$s$^{-1}$ in the ATLAS and CMS experiments. With higher luminosity, more proton–proton interactions will happen in each bunch crossing, with pileup reaching up to 200, making track reconstruction much more challenging.

We calculate the two-point massless QCD correlator of nonlocal composite vector quark currents with chains of fermion one-loop radiative corrections inserted into the gluon lines. The correlator depends on the Bjorken fraction $x$ related to the composite current and, in the large-$\beta_0$ approximation, provides the dominant contributions in each order of perturbation theory.
