Chiral symmetry restoration and the critical end point in QCD

open access: yesOpen Physics, 2017
In a system of quark matter we study the chiral phase transition, the behavior of the chiral and quark number susceptibility and the CEP at finite temperature and chemical potential.

Comparative Analysis of Machine Learning Models for Predicting Travel Time [PDF]

open access: yesarXiv, 2021
In this paper, five different deep learning models are being compared for predicting travel time. These models are autoregressive integrated moving average (ARIMA) model, recurrent neural network (RNN) model, autoregressive (AR) model, Long-short term memory (LSTM) model, and gated recurrent units (GRU) model.

Two Higgs Doublets, a 4th Generation and a 125 GeV Higgs: A Review

open access: yesAdvances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
We review the possible role that multi‐Higgs models may play in our understanding of the dynamics of a heavy 4th sequential generation of fermions. We describe the underlying ingredients of such models, focusing on two Higgs doublets, and discuss how they may effectively accommodate the low‐energy phenomenology of such new heavy fermionic degrees of ...

Model Validation in Ontology Based Transformations [PDF]

open access: yesEPTCS 98, 2012, pp. 17-30, 2012
Model Driven Engineering (MDE) is an emerging approach of software engineering. MDE emphasizes the construction of models from which the implementation should be derived by applying model transformations. The Ontology Definition Meta-model (ODM) has been proposed as a profile for UML models of the Web Ontology Language (OWL).

Yukawa Bound States and Their LHC Phenomenology

open access: yesAdvances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
We present the current status on the possible bound states of extra generation quarks. These include phenomenology and search strategy at the LHC. If chiral fourth‐generation quarks do exist their strong Yukawa couplings, implied by current experimental lower bound on their masses, may lead to formation of bound states.

Model Selection for Explosive Models [PDF]

open access: yesAdvances in Econometrics, Vol. 41, 2020, pp. 73-103, 2017
This paper examines the limit properties of information criteria (such as AIC, BIC, HQIC) for distinguishing between the unit root model and the various kinds of explosive models. The explosive models include the local-to-unit-root model, the mildly explosive model and the regular explosive model.

Search of QCD phase transition points in the canonical approach of the NJL model

open access: yesPhysics Letters B, 2019
We study the Lee-Yang zeros in the canonical approach to search phase transition points at finite temperature and density in the Nambu-Jona-Lasinio (NJL) model as an effective model of QCD.

Equation of State for Dense Matter with a QCD Phase Transition

open access: yesUniverse, 2018
We construct a dense matter equation of state (EoS) starting from a hadronic density dependent relativistic mean-field model with a DD2 parametrization including the excluded volume corrections at low densities.

Yukawa interactions at large charge

open access: yesJournal of High Energy Physics, 2022
We extend the fixed-charge semiclassical method by computing anomalous dimensions of fixed-charge scalar operators in models with Yukawa interactions. In particular, we discuss the Nambu-Jona-Lasinio-Yukawa theory as well as an asymptotically safe gauge ...

A Taxonomy of Polytomous Item Response Models [PDF]

open access: yesarXiv, 2020
A common framework is provided that comprises classical ordinal item response models as the cumulative, sequential and adjacent categories models as well as nominal response models and item response tree models. The taxonomy is based on the ways binary models can be seen as building blocks of the various models.
