recommendations! Published in 2019 at "Journal of High Energy Physics"

DOI: 10.1007/jhep02(2019)094

Abstract: A bstractWe introduce high-energy limits which allow us to derive recursion relations fixing the various couplings of Lagrangians of two-dimensional relativistic quantum field theories with no tree-level particle production in a very straightforward way. The… read more here.

DOI: 10.1007/jhep05(2025)077

Abstract: Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massive scalars in an effort to fully understand the… read more here.

DOI: 10.1007/jhep07(2024)100

Abstract: Inspired by the picture portraying the KNO scaling violation as an extension of the geometrical scaling violation, the current study proposes a phenomenological model for multi-particle production in hadron collisions based on the geometrical approach… read more here.

DOI: 10.1007/jhep10(2019)129

Abstract: Abstract Hiscock and Weems showed that under Hawking evaporation, an isolated asymptotically flat Reissner-Nordström (RN) black hole evolves in a surprising manner: if it starts with a relatively small value of charge-to-mass ratio Q/M, then… read more here.

DOI: 10.1007/jhep11(2021)146

Abstract: Abstract Analytic and numerical techniques are presented for computing gravitational production of scalar particles in the limit that the inflaton mass is much larger than the Hubble expansion rate at the end of inflation. These… read more here.

DOI: 10.1021/acs.est.7b03596

Abstract: Personal care products (PCP) might be a source of ultrafine particle exposure for users owing to the reaction of ozone with terpene ingredients. The near-person emissions associated with PCP may contribute to exposures that would… read more here.

DOI: 10.1088/1475-7516/2021/09/009

Abstract: We discuss the adiabatic basis dependence of particle number in time-dependent backgrounds. In particular, we focus on preheating after inflation, and show that, for the optimal basis, the time dependence of the produced particle number… read more here.

DOI: 10.1088/1475-7516/2023/04/058

Abstract: We examine a type of feature in the primordial scalar power spectrum, namely, the bump-like feature(s) that arise as a result of burst(s) of particle production during inflation. The latest CMB observations by Planck 2018… read more here.

DOI: 10.1088/1751-8121/accb1e

Abstract: We prove factorization of the generating functional of connected tree diagrams by exploring that it is the Legendre transform of the action. This theorem is then applied to the example of a local relativistic interacting… read more here.
