Efectos de Temperatura Finita y Curvatura en QCD y Modelos de Quarks Quirales
Eugenio Megias
We develop the heat kernel method in the context of finite temperature quantum field theory. We compute the heat kernel expansion in the presence of general gauge and scalar fields…
Thermal shifts, fluctuations, and missing states
Enrique Ruiz Arriola, Wojciech Broniowski, Eugenio Megias +1
Thermal shifts and fluctuations at finite temperature below the deconfinement crossover from hadronic matter to the quark-gluon plasma provide a viable way to search for missing st…
Heavy Quark Coupled Channel Dynamics from Thermal Shifts
Enrique Ruiz Arriola, Lorenzo Luis Salcedo, Eugenio Megias
QCD at finite temperature below the phase transition should be determined in terms of colour singlet states such as hadrons and strings. We show how quark-hadron duality allows ext…
Fractal aspects of hadrons
Airton Deppman, Eugenio Megias
The non extensive aspects of distributions obtained in high energy collisions are discussed in relation to possible fractal structure in hadrons, in the sense of the thermofr…
Light dilatons in warped space: Higgs boson and LHCb anomalies
Eugenio Megias, Giuliano Panico, Oriol Pujolas +1
We study the extension of the Standard Model (SM) with a light dilaton in a five dimensional warped model. In particular, we analyze the coupling of the dilaton with the SM matter…
A Natural origin for the LHCb anomalies
Eugenio Megias, Giuliano Panico, Oriol Pujolas +1
The anomalies recently found by the LHCb collaboration in -meson decays seem to point towards the existence of new physics coupled non-universally to muons and electrons. We sho…
Heavy Quark Entropy shift: From the Hadron Resonance Gas to Power Corrections
E. Megias, E. Ruiz Arriola, L. L. Salcedo
A heavy quark placed in the medium modifies its specific heat. Using a renormalization group argument we show a low energy theorem in terms of the defect in the trace of the energy…
Heavy quark-antiquark free energy and thermodynamics of string-hadron avoided crossings
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The correlation function between two Polyakov loops encodes the free-energy shift due to a pair of separated colour conjugated sources in the hot QCD medium. This is analyzed in te…
On dilatons and the LHC diphoton excess
Eugenio Megias, Oriol Pujolas, Mariano Quiros
We study soft wall models that can embed the Standard Model and a naturally light dilaton. Exploiting the full capabilities of these models we identify the parameter space that all…
