Which dark matter for which experiment? / Tytgat, Michel H G (Brussels U.)
In this talk I gave in Moriond, I spoke about the current status of the WIMP as dark matter, about some simple extensions, and about a FIMP as a possible alternative. I focused on their possible experimental signatures and also, to some extent, on their shortcomings..

Large N$_(c')$, chiral approach to M$_(n')$ at finite temperature / Escribano, R (INFN-Laboratori Nazionali di Frascati, Italy) ; Ling, F S (Université Libre de Bruxelles, Belgium) ; Tytgat, M H G (CERN)
We study the temperature dependence of the eta and eta[prime] meson masses within the framework of U(3)L×U(3)R chiral perturbation theory, up to next-to-leading order in a simultaneous expansion in momenta, quark masses and number of colors. We find that both masses decrease at low temperatures, but only very slightly. [...]

Instability of Non-Commutative SYM Theories at Finite Temperature / Landsteiner, Karl (CERN) ; Lopez, Esperanza (CERN) ; Tytgat, Michel H.G. (Brussels U.)
We extend our previous work on the quasi-particle excitations in N=4 non-commutative U(1) Yang-Mills theory at finite temperature. We show that above some critical temperature there is a tachyon in the spectrum of excitations. [...]

Sum Rules in the CFL Phase of QCD at finite density / Manuel, Cristina (CERN) ; Tytgat, Michel H.G. (CERN)
We study the asymmetry between the vector current and axial-vector current correlators in the colour-flavour locking (CFL) phase of QCD at finite density. Using Weinberg's sum rules, we compute the decay constant $f_\pi$ of the Goldstone modes and find agreement with previous derivations. [...]

Excitations in Hot Non-Commutative Theories / Landsteiner, Karl (CERN) ; Lopez, Esperanza (CERN) ; Tytgat, Michel H.G. (CERN)
We study the dispersion relation for scalar excitations in supersymmetric, non-commutative theories at finite temperature. In N=4 Yang-Mills the low momenta modes have superluminous group velocity. [...]

Large $N_{c}$, chiral approach to $M_{\eta}'$ at finite temperature / Escribano, R. (Frascati) ; Ling, F.S. (Brussels U.) ; Tytgat, M.H.G. (CERN)
We study the temperature dependence of the eta and eta' meson masses within the framework of U(3)_L x U(3)_R chiral perturbation theory, up to next-to-leading order in a simultaneous expansion in momenta, quark masses and number of colours. We find that both masses decrease at low temperatures, but only very slightly. [...]

Anomalous processes at high temperature and density in a 2-dimensional linear $\sigma$ model / Gelis, Francois (Brookhaven) ; Tytgat, Michel H.G. (CERN)
We use the 2-dimensional $\sigma$ model as a toy model to study the behavior of anomalous amplitudes in the limit where the constituent quark mass is small. Symmetry arguments tell that the $\pi^o\to\gamma$ amplitude should vanish if $m\to 0$, but we show that this conclusion is spoiled by infrared singularities. [...]

Masses of the Goldstone modes in the CFL phase of QCD at finite density / Manuel, C ; Tytgat, M H G
We construct the U_L(3) x U_R(3) effective lagrangian which encodes the dynamics of the low energy pseudoscalar excitations in the Color-Flavor-Locking superconducting phase of QCD at finite quark density. We include the effects of instanton-induced interactions and study the mass pattern of the pseudoscalar mesons. [...]

Effective field theory approach to N=4 supersymmetric Yang-Mills at finite temperature / Nieto, Agustin (CERN) ; Tytgat, Michel H.G. (Brussels U.)
We study the perturbation expansion of the free energy of N=4 supersymmetric SU(N) Yang-Mills at finite temperature in powers of 't Hooft's coupling g^2 N in the large N limit. [...]
