Nudžeim Selimović: Topological Portal to the Dark Sector

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (F1 tea room)

I will discuss a novel topological portal between quantum chromodynamics (QCD) and a dark QCD-like sector. Such a portal is present only for a unique coset structure after QCD confinement and it connects three QCD to two dark pions. When … Read More

Somiealo Azote, “Quantitative Predictions of biomechanical drivers of cell delamination in stratified epithelia (skin epidermis) using a dynamic 3D vertex model”

C/2-X - F1 čajnica (Jamova)

Speakers: Somiealo Azote During embryonic development, the skin epidermis gradually transitions from a single layer of stem cells to a stratified, multi-layered tissue. This process involves the coordinated differentiation and upward movement of basal cells, known as delamination. It is … Read More

Shoji, Baratella: The Standard Model lifetime is slightly shorter

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (F1 tea room)

We revisit the decay rate of the electroweak vacuum in the Standard Model with the full one-loop prefactor. We focus on the gauge degrees of freedom and derive the degeneracy factors appearing in the functional determinant using group theoretical arguments. … Read More

Pietro Baratella: Journal Club on WZW terms without anomalies: generalised symmetries in chiral Lagrangians

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (F1 tea room)

Journal Club on WZW terms without anomalies: generalised symmetries in chiral Lagrangians (arXiv:2407.20340)Abstract:We consider a 4d non-linear sigma model on the coset $(text{SU}(N)_L times text{SU}(N)_R times text{SU}(2))/(text{SU}(N)_{L+R}times text{U})cong text{SU}(N) times S^2$, that features a topological Wess--Zumino--Witten (WZW) term whose curvature … Read More

Joshua Lockyer: Exploring near-conformal dark sector theories

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (A/1-106 - Seminarska soba fizike (F5))

Dark-showers offer a compelling collider signature for Hidden Valley models featuring a confining dark sector. Our work extends the investigation of these models to near-conformal theories where the running coupling, controlled by renormalization group equations (RGE), flows near to an … Read More
