Tensionless Strings from Worldsheet Symmetries [PDF]

, 2015
We revisit the construction of the tensionless limit of closed bosonic string theory in the covariant formulation in the light of Galilean conformal symmetry that rises as the residual gauge symmetry on the tensionless worldsheet.

Evidence for Winding States in Noncommutative Quantum Field Theory [PDF]

, 2000
We study noncommutative field theories at finite temperature to learn more about the degrees of freedom in the non-planar sector of these systems. We find evidence for winding states.

A perspective on Quantum Gravity Phenomenology [PDF]

, 2003
I give a brief overview of some Quantum-Gravity-Phenomenology research lines, focusing on studies of cosmic rays and gamma-ray bursts that concern the fate of Lorentz symmetry in quantum spacetime.

On a Missed Mechanism of Dielectron Production in Nucleon-Nucleon Collisions

, 2010
We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to \gamma^\star d^\star_1$, where $\gamma^\star$ is the virtual photon which converts ...

Brane-Antibrane Inflation in Orbifold and Orientifold Models [PDF]

, 2001
We analyse the cosmological implications of brane-antibrane systems in string-theoretic orbifold and orientifold models. In a class of realistic models, consistency conditions require branes and antibranes to be stuck at different fixed points, and so ...

Cosmological perturbations and short distance physics from Noncommutative Geometry [PDF]

, 2002
We investigate the possible effects on the evolution of perturbations in the inflationary epoch due to short distance physics. We introduce a suitable non local action for the inflaton field, suggested by Noncommutative Geometry, and obtained by adopting

Finetuning foundation models for joint analysis optimization in High Energy Physics [PDF]

Machine Learning: Science and Technology
In this work we demonstrate that significant gains in performance and data efficiency can be achieved in High Energy Physics (HEP) by moving beyond the standard paradigm of sequential optimization or reconstruction and analysis components.

Circulating fatty acid binding protein 4 (FABP‐4) concentrations and mortality in individuals with colorectal cancer in the European Prospective Investigation into Cancer and Nutrition study

International Journal of Cancer, EarlyView.
What's New? Higher pre‐diagnostic body mass index has been associated with higher risk of mortality in individuals with colorectal cancer; however, the mechanism remains unclear. This prospective analysis of incident colorectal cancer cases within the European Prospective Investigation into Cancer and Nutrition cohort study addressed potential collider

TeV-Scale strings

, 2014
This article discusses the status of string physics where the string tension is around the TeV scale. The article covers model building basics for perturbative strings, based on D-brane configurations. The effective low energy physics description of such

Masked particle modeling on sets: towards self-supervised high energy physics foundation models [PDF]

Machine Learning: Science and Technology
We propose masked particle modeling (MPM) as a self-supervised method for learning generic, transferable, and reusable representations on unordered sets of inputs for use in high energy physics (HEP) scientific data.
