1. a-theorem at large Nf / Antipin, Oleg ; Dondi, Nicola Andrea ; Sannino, Francesco ; Thomsen, Anders Eller
We determine the Jack and Osborn a-function and related metric for gauge-fermion theories to leading order in the large number of fermions and to all orders in the gauge coupling, demonstrating that the strong a-theorem is violated for the minimal choice of the a-function..

3. Conformal window 2.0: The large Nf safe story / Antipin, Oleg ; Sannino, Francesco
We extend the phase diagram of SU(N) gauge-fermion theories as a function of the number of flavors and colors to the region in which asymptotic freedom is lost. [...]

4. Revisiting the decoupling effects in the running of the Cosmological Constant / Antipin, Oleg ; Melić, Blaženka
We revisit the decoupling effects associated with heavy particles in the renormalization group running of the vacuum energy in a mass-dependent renormalization scheme. [...]

7. Accidental composite dark matter / Antipin, Oleg ; Redi, Michele ; Strumia, Alessandro ; Vigiani, Elena
We build models where Dark Matter candidates arise as composite states of a new confining gauge force, stable thanks to accidental symmetries. [...]

9. Dynamical generation of the weak and Dark Matter scales from strong interactions / Antipin, Oleg ; Redi, Michele ; Strumia, Alessandro
Assuming that mass scales arise in nature only via dimensional transmutation, we extend the dimension-less Standard Model by adding vector-like fermions charged under a new strong gauge interaction. [...]

10. S table Eχ tensions with(out) gravity / Antipin, Oleg ; Krog, Jens ; Mojaza, Matin ; Sannino, Francesco
We investigate the vacuum stability as well as the gravitational corrections in extensions of the Standard Model featuring a new complex scalar, and two Dirac fermions for different choices of the hypercharge of the scalar and one of the two fermions. [...]
