29. Vortex states as a novel tool for nuclear and particle physics

Prof. Igor Ivanov (Sun Yat-sen University, Zhuhai, China)

9/16/25, 10:25 AM

In particle physics, we usually describe particle collisions in terms of plane waves. With very few exceptions, the fact that the initial-state particles are in fact wave packets does not lead to any modification of theoretical and experimental analysis. However, there is a very interesting class of wave packets called vortex states, collisions of which offer a wealth of novel opportunities...

31. A decade of GW detections... and much more to come!

Giacomo Ciani

Ten years ago, the LIGO-Virgo collaboration detected the first-ever gravitational wave signal, produced by a pair of coalescing black holes. Since then, detector sensitivities have improved, detections have multiplied, and long-standing assumptions in astronomy and astrophysics have been challenged. With now over 200 confirmed GW signal candidates and new detections arriving at a rate of about...

44. Effective interaction of vector bosons of the SM expansion of the Chern-Simons type with fermions of the Standard Model

Volodymyr Gorkavenko (Taras Shevchenko National University of Kyiv)

9/16/25, 11:55 AM

We consider the vector extension of the Standard Model (SM) with Chern-Simons (CS) type interaction. This extension contains a new massive vector boson $X_\mu$ (Chern-Simons boson). The minimal gauge-invariant Lagrangian of the interaction with SM particles has the form of 6-dimension operators
\begin{align}
\mathcal{L}1&=\frac{C_Y}{\Lambda_Y^2}\cdot X\mu (\mathfrak D_\nu H)^\dagger...

34. The scalar sector in the Georgi-Machacek model

Amine Ahriche (University of Sharjah (AE))

9/16/25, 12:20 PM

The Georgi-Machacek (GM) model extends the Standard Model with a scalar sector that predicts exotic Higgs states while preserving a custodial symmetry. Here, we make a comprehensive analysis of the model’s viability and its potential to explain intriguing LHC and LEP data. We show that theoretical constraints are decisive: the requirement that our vacuum is the true global minimum excludes...

50. New results on $\phi$(1020) production from the NA61/SHINE experiment at CERN SPS

Antoni Marcinek (Polish Academy of Sciences (PL))

9/16/25, 12:45 PM

NA61/SHINE is a multi-purpose, fixed-target hadron spectrometer at the CERN SPS. Its research program includes studies of strong interactions as well as reference measurements for neutrino and cosmic-ray physics. A significant advantage of NA61/SHINE over collider experiments is its extended coverage of phase space available for particle production. This includes the entire projectile...

21. Highlights from the Pierre Auger Observatory

Laura Valore

9/16/25, 1:10 PM

The Pierre Auger Observatory is the world’s largest operating facility for ultra-high-energy cosmic ray (UHECR) detection, combining 1,660 surface water-Cherenkov detectors with 27 fluorescence telescopes in a hybrid design. With the ongoing AugerPrime upgrade, featuring new scintillator detectors and improved electronics, the Observatory is enhancing its sensitivity to primary mass...

20. AugerPrime and the Onset of Phase II at the Pierre Auger Observatory

Dr Gabriella Cataldi (INFN Lecce - Italy)

9/16/25, 1:35 PM

The upgrade of the Pierre Auger Observatory, known as AugerPrime, has been successfully completed, marking the beginning of Phase II data-taking. With the commissioning of the new components finalized,the Observatory is now fully operational and prepared to pursue its enhanced scientific goals. The Pierre Auger Observatory has already provided high-precision evidence for the suppression in the...
