Title The International Linear Collider Project-Its Physics and Status Type Journal Article
Year 2021 Publication (down) Symmetry-Basel Abbreviated Journal Symmetry-Basel
Volume 13 Issue 4 Pages 674 - 15pp
Keywords Higgs particle; elementary particles; standard theory; linear collider; dark matter; top quark
Abstract The discovery of Higgs particle has ushered in a new era of particle physics. Even though the list of members of the standard theory of particle physics is now complete, the shortcomings of the theory became ever more acute. It is generally considered that the best solution to the problems is an electron-positron collider that can study Higgs particle with high precision and high sensitivity; namely, a Higgs factory. Among a few candidates for Higgs factory, the International Linear Collider (ILC) is currently the most advanced in its program. In this article, we review the physics and the project status of the ILC including its energy expandability.

Title Analysis of the Internal Structure of Hadrons Using Direct Photon Production Type Journal Article
Year 2021 Publication (down) Symmetry-Basel Abbreviated Journal Symmetry-Basel
Volume 13 Issue 6 Pages 942 - 10pp
Keywords
Abstract Achieving a precise description of the internal structure of hadrons is crucial for deciphering the hidden properties and symmetries of fundamental particles. It is a hard task since there are several bottlenecks in obtaining theoretical predictions starting from first principles. In order to complement highly accurate experiments, it is necessary to use ingenious strategies to impose constraints from the theory side. In this article, we describe how photons can be used to unveil the internal structure of hadrons. We explore how to describe NLO QCD plus LO QED corrections to hadron plus photon production at colliders and discuss the impact of these effects on the experimental measurements.

Title A Stroll through the Loop-Tree Duality Type Journal Article
Year 2021 Publication (down) Symmetry-Basel Abbreviated Journal Symmetry-Basel
Volume 13 Issue 6 Pages 1029 - 37pp
Keywords Feynman integrals; multi-loop calculations; perturbative QFT; higher orders
Abstract The Loop-Tree Duality (LTD) theorem is an innovative technique to deal with multi-loop scattering amplitudes, leading to integrand-level representations over a Euclidean space. In this article, we review the last developments concerning this framework, focusing on the manifestly causal representation of multi-loop Feynman integrals and scattering amplitudes, and the definition of dual local counter-terms to cancel infrared singularities.

Title Exploring QED Effects to Diphoton Production at Hadron Colliders Type Journal Article
Year 2021 Publication (down) Symmetry-Basel Abbreviated Journal Symmetry-Basel
Volume 13 Issue 6 Pages 994 - 17pp
Keywords diphoton production; QCD corrections; NLO calculations; QED effects
Abstract In this article, we report phenomenological studies about the impact of O(alpha) corrections to diphoton production at hadron colliders. We explore the application of the Abelianized version of the qT-subtraction method to efficiently compute NLO QED contributions, taking advantage of the symmetries relating QCD and QED corrections. We analyze the experimental consequences due to the selection criteria and we find percent-level deviations for M-gamma gamma > 1TeV. An accurate description of the tail of the invariant mass distribution is very important for new physics searches which have the diphoton process as one of their main backgrounds. Moreover, we emphasize the importance of properly dealing with the observable photons by reproducing the experimental conditions applied to the event reconstruction.

Title Quantum Supertwistors Type Journal Article
Year 2021 Publication (down) Symmetry-Basel Abbreviated Journal Symmetry-Basel
Volume 13 Issue 7 Pages 1241 - 16pp
Keywords star products; superspace; non-commutative spacetime; quantum groups; quantum supergroups
Abstract In this paper, we give an explicit expression for a star product on the super-Minkowski space written in the supertwistor formalism. The big cell of the super-Grassmannian Gr(2|0,4|1) is identified with the chiral, super-Minkowski space. The super-Grassmannian is a homogeneous space under the action of the complexification SL(4|1) of SU(2,2|1), the superconformal group in dimension 4, signature (1,3), and supersymmetry N=1. The quantization is done by substituting the groups and homogeneous spaces by their quantum deformed counterparts. The calculations are done in Manin's formalism. When we restrict to the big cell, we can explicitly compute an expression for the super-star product in the Minkowski superspace associated to this deformation and the choice of a certain basis of monomials.
