The Standard Model of Electroweak Interactions [PDF]

open access: yes, 2007
Gauge invariance is a powerful tool to determine the dynamics of the electroweak and strong forces. The particle content, structure and symmetries of the Standard Model Lagrangian are discussed.

High Energy Physics and Cosmology as Computation

open access: yes, 2016
The present paper is basically written as a non-apologetic strong defence of the thesis that computation is part and parcel of a physical theory and by no means a mere numerical evaluation of the prediction of a theory which comes towards the end ...

New Physics at High-Energy: An Effective-Theory Approach

open access: yes, 2022
In this document I summarise the main research results carried out during my Ph.D. at University of Geneva, in the period 2018-2022, under the supervision of Prof. Francesco Riva. My published works represent the main content of this document. Along with them the initial chapter largely introduces their context, aims, methods and results.

High energy cosmic-rays: puzzles, models, and giga-ton neutrino telescopes [PDF]

open access: yesPramana 62 (2004) 483-496, 2003
The existence of cosmic rays of energies exceeding 10^20 eV is one of the mysteries of high energy astrophysics. The spectrum and the high energy to which it extends rule out almost all suggested source models. The challenges posed by observations to models for the origin of high energy cosmic rays are reviewed, and the implications of recent new ...

Trace Anomaly and Quantization of Maxwell's Theory on Non-Commutative Spaces

open access: yes, 2002
The canonical and symmetrical energy-momentum tensors and their non-zero traces in Maxwell's theory on non-commutative spaces have been found. Dirac's quantization of the theory under consideration has been performed.

Zero-norm states and stringy symmetries

open access: yes, 2005
We identify spacetime symmetry charges of 26D open bosonic string theory from an infinite number of zero-norm states (ZNS) with arbitrary high spin in the old covariant first quantized string spectrum.

Do high-energy neutrinos travel faster than photons in a discrete space-time? [PDF]

open access: yes, 2011
The recent OPERA measurement of high-energy neutrino velocity, once independently verified, implies new physics in the neutrino sector. We revisit the theoretical inconsistency of the fundamental high-energy cutoff attributing to quantum gravity with the

High-energy limit of mass-suppressed amplitudes in gauge theories [PDF]

open access: yesJournal of High Energy Physics, 2018
We present a detailed analysis of the factorization and all-order resummation of the double-logarithmic radiative corrections which determine the asymptotic behavior of the gauge theory amplitudes suppressed by the leading power of the fermion mass in ...
