Understanding the and masses as well as their widths
Eef van Beveren, George Rupp
The low and approximately equal masses of the scalar mesons and , as well as their relatively small decay widths, are impossible to understand in terms of stan…
Warm Inflation, Neutrinos and Dark matter: a minimal extension of the Standard Model
Miguel Levy, João G. Rosa, Luis B. Ventura
We show that warm inflation can be realized within a minimal extension of the Standard Model with three right-handed neutrinos, three complex scalars and a gauged lepton/B-L U(1) s…
Modern meson spectroscopy: the fundamental role of unitarity
Eef van Beveren, George Rupp
The importance of -matrix unitarity in realistic meson spectroscopy is reviewed, both its historical development and more recent applications. First the effects of imposing -…
Critical properties of calibrated relativistic mean-field models for the transition to warm, non-homogeneous nuclear matter
Olfa Boukari, Helena Pais, Sofija Antić +1
The critical properties for the transition to warm, asymmetric, non-homogeneous nuclear matter are analysed within a thermodynamical spinodal approach for a set of well calibrated…
Two-loop renormalisation of gauge theories in Implicit Regularisation and connections to dimensional methods
A. Cherchiglia, D. C. Arias-Perdomo, A. R. Vieira +2
We compute the two-loop -function of scalar and spinorial quantum electrodynamics as well as pure Yang-Mills and quantum chromodynamics using the background field method in a fu…
Neutron star cooling within the equation of state with induced surface tension
Stefanos Tsiopelas, Violetta Sagun
We study the thermal evolution of neutron stars described within the equation of state with induced surface tension (IST) that reproduces properties of normal nuclear matter, fulfi…
Second virial coefficients of light nuclear clusters and their chemical freeze-out in nuclear collisions
K. A. Bugaev, O. V. Vitiuk, B. E. Grinyuk +13
Here we develop a new strategy to analyze the chemical freeze-out of light (anti)nuclei produced in high energy collisions of heavy atomic nuclei within an advanced version of the…
Superradiant pion clouds around primordial black holes
Paulo B. Ferraz, Thomas W. Kephart, João G. Rosa
We show that highly spinning primordial black holes of mass kg, potentially born in a matter-dominated era after inflation, can produce clouds of pions in their vic…
Discovery and characterization of the exoplanets WASP-148b and c. A transiting system with two interacting giant planets
G. Hebrard, R. F. Diaz, A. C. M. Correia +39
We present the discovery and characterization of WASP-148, a new extrasolar system that includes at least two giant planets. The host star is a slowly rotating inactive late-G dwar…
The Neutron Star Outer Crust Equation of State: A Machine Learning approach
Murarka Utsav Anil, Kinjal Banerjee, Tuhin Malik +1
Constructing the outer crust of the neutron stars requires the knowledge of the Binding Energy (BE) of the atomic nuclei. Although the BE of a lot of the nuclei is experimentally d…
Classical excluded volumes of loosely bound light (anti)nuclei and their chemical freeze-out in heavy ion collisions
B. E. Grinyuk, K. A. Bugaev, V. V. Sagun +12
From the analysis of light (anti)nuclei multiplicities that were measured recently by the ALICE collaboration in Pb+Pb collisions at the center-of-mass collision energy $\sqrt{s_{N…
One-meson-loop NJL model: Effect of collective and noncollective excitations on the quark condensate at finite temperature
Renan Câmara Pereira, Pedro Costa
We explore the effect of including quantum fluctuations in the two flavor NambuJona-Lasinio model at finite temperature. This is accomplished, in a symmetry preserving way, by i…
Non-zero tensor condensates in cold quark matter within the three-flavor Nambu-Jona-Lasinio model with the Kobayashi-Maskawa-'t Hooft interaction
A. Kagawa, M. Morimoto, Y. Tsue +3
The possible formation of tensor condensates originated from a tensor-type interaction between quarks is investigated in the three-flavor Nambu-Jona-Lasinio model including the Kob…
Functional renormalization group study of the critical region of the quark-meson model with vector interactions
Renan Câmara Pereira, Rainer Stiele, Pedro Costa
The critical region of the two flavour quark-meson model with vector interactions is explored using the Functional Renormalization Group technique, a non-perturbative method that t…
Asteroseismology: radial oscillations of neutron stars with realistic equation of state
V. Sagun, G. Panotopoulos, I. Lopes
We study radial oscillations of non-rotating neutron stars (NSs) in four-dimensional General Relativity. The interior of the NS was modelled within a recently proposed multicompone…
Search for dijet resonances in events with an isolated charged lepton using TeV proton-proton collision data collected by the ATLAS detector
ATLAS Collaboration
A search for dijet resonances in events with at least one isolated charged lepton is performed using of TeV proton-proton collision data record…
