The 2025 Phenomenology Symposium (PHENO) will be held May 19 - 21, 2025 at the University of Pittsburgh. It will cover the latest topics in particle phenomenology and theory as well as related issues ...

This conference explores the intersection of HEP and environmental sustainability over 4 days. Two days in a more Europe/Africa/Asia/Australia friendly time zone and ...

A possible explanation of mass hierarchy, which is not explained by the Standard Model, is that quarks and leptons are composite objects made of more fundamental particles known as preons. The ...

Polarization effects are considered in colliding γe and γγ beams, which are proposed to be obtained on the basis of linear e + e − colliders (by backward Compton scattering of laser light on electron ...

If high energy heavy ion collisions lead to the formation of a hot quark-gluon plasma, then colour screening prevents cc binding in the deconfined interior of the interaction region. To study this ...

The requirement that P and T be approximately conserved in the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed. Several possibilities are identified, ...

We consider the three-dimensional Dirac equation in spherical coordinates with coupling to static electromagnetic potential. The space components of the potential have angular (non-central) dependence ...

We formulate the geometric quantization of Teichmüller space by using its relation with SL(2, R ) Chern-Simons gauge theory and show that the physical state conditions arising in this formalism are ...

If new particles are gauged by a new U(1) then their electromagnetic charges may be shifted by a calculable amount.

Search for additional scalar bosons within the Inert Doublet Model in a final state with two leptons at the FCC-ee ...

We compute the four-loop ( O ( α ′ 4 )) metric β-function for the two-dimensional bosonic non-linear σ-model. We employ an indirect method which avoids a large part of the explicit calculation and as ...
