A Physics Enhanced Residual Learning (PERL) Framework for Vehicle Trajectory Prediction [PDF]
arXiv, 2023 In vehicle trajectory prediction, physics models and data-driven models are two predominant methodologies. However, each approach presents its own set of challenges: physics models fall short in predictability, while data-driven models lack interpretability.

Bethe Ansatz in Stringy Sigma Models [PDF]
J.Stat.Mech.0605:P05006,2006, 2006 We compute the exact S-matrix and give the Bethe ansatz solution for three sigma-models which arise as subsectors of string theory in AdS(5)xS(5): Landau-Lifshitz model (non-relativistic sigma-model on S(2)), Alday-Arutyunov-Frolov model (fermionic sigma-model with su(1|1) symmetry), and Faddeev-Reshetikhin model (string sigma-model on S(3)xR).

On SU(3) Effective Models and Chiral Phase Transition
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 Sensitivity of Polyakov Nambu‐Jona‐Lasinio (PNJL) model and Polyakov linear sigma‐model (PLSM) has been utilized in studying QCD phase‐diagram. From quasi‐particle model (QPM) a gluonic sector is integrated into LSM. The hadron resonance gas (HRG) model is used in calculating the thermal and dense dependence of quark‐antiquark condensate.

A proposal of a renormalizable Nambu–Jona-Lasinio model
European Physical Journal C: Particles and Fields, 2018 A local and gauge invariant gauge field model including Nambu–Jona-Lasinio (NJL) and QCD Lagrangian terms in its action is introduced. Surprisingly, it becomes power counting renormalizable. This occurs thanks to the presence of action terms which modify

Physics Research International, Volume 2014, Issue 1, 2014., 2014 A baryonic chemical potential (μb) is included in the linear sigma model at finite temperature. The effective mesonic potential is numerically calculated using the N‐midpoint rule. The meson masses are investigated as functions of the temperature (T) at fixed value of baryonic chemical potential.

Inverse magnetic catalysis in Nambu–Jona-Lasinio model beyond mean field
Physics Letters B, 2016 We study inverse magnetic catalysis in the Nambu–Jona-Lasinio model beyond mean field approximation. The feed-down from mesons to quarks is embedded in an effective coupling constant at finite temperature and magnetic field.

Quantum simulation of chiral phase transitions
Journal of High Energy Physics, 2022 The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign ...

Non Proportional Odds Models are Widely Dispensable -- Sparser Modeling based on Parametric and Additive Location-Shift Approaches [PDF]
arXiv, 2020 The potential of location-shift models to find adequate models between the proportional odds model and the non-proportional odds model is investigated. It is demonstrated that these models are very useful in ordinal modeling. While proportional odds models are often too simple, non proportional odds models are typically unnecessary complicated and seem

Dynamical Electroweak Symmetry Breaking with a Heavy Fermion in Light of Recent LHC Results
Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013 The recent announcement of a discovery of a possible Higgs‐like particle—its spin and parity are yet to be determined—at the LHC with a mass of 126 GeV necessitates a fresh look at the nature of the electroweak symmetry breaking, in particular if this newly‐discovered particle will turn out to have the quantum numbers of a Standard Model Higgs boson ...

Bootstrap Dynamical Symmetry Breaking
Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013 Despite the emergence of a 125 GeV Higgs‐like particle at the LHC, we explore the possibility of dynamical electroweak symmetry breaking by strong Yukawa coupling of very heavy new chiral quarks Q. Taking the 125 GeV object to be a dilaton with suppressed couplings, we note that the Goldstone bosons G exist as longitudinal modes VL of the weak bosons ...
