- \begin{frame}\frametitle{Rare decays theory in a nutshell}
- {~}\\
- Typically one describes those decays in Heavy Quark Effective Field Theory(EFT) framework, where we sacrifice the beauty of substructure of the decays. The point like interaction is described by a Hamiltonian:
- \begin{align*}
- \mathcal{H} \sim \mathcal{M}_{CKM} \sum_i \mathcal{C}_i \mathcal{O}_i
- \end{align*}
-
- Each decay contains only a couple of operators ($\mathcal{O}$) that contribute in the decay. NP searches are done by measuring the Willson coefficients: $\mathcal{C}_i = \mathcal{C}^{SM}_i+\mathcal{C}^{NP}_i$.\\
-
- Measurement $\mathcal{C}_i \Rightarrow$ constrains on NP models

- \begin{frame}\frametitle{Run2 data}
- $\Rrightarrow$ We should be prepared for Run2 data, however:
- \begin{itemize}
- \item Run1 is still not fully exploited!
- \item Analysis are still ongoing.
- \item Run2 data will be usable when we collect ($ \sim 2$) times the statistics of Run1.
- \item Finally Run1 data is understood, Run2 is an unexplored land.
- \end{itemize}
-
- $\Rrightarrow$ To sum up: For another year or two we will still use the Run1 data for most of the NP searches.
-
- \end{frame}
-
- \begin{frame}\frametitle{Plans for the future?}
- $\Rrightarrow$ So let's list the hints of NP we have:
- \begin{itemize}
- \item The famous $P_5^{\prime}$ anomaly ($3.7~\sigma$).
- \item The $R_k$ anomaly ($2.7~\sigma$).
- \item The $R(\PDstar)$ anomaly ($2.1~\sigma$)\footnote{This anomaly was also observed by Babar and Belle with $2.7~\sigma$ and $2.0\sigma$ significance.}.
- \end{itemize}
- $\Rrightarrow$ For fun let's assume that these anomalies are not just statistics fluctuation but nature showing its true face.
-
- \begin{itemize}
- \item All hints point out that there is clear indication that NP clearly violates lepton universality.
- \item There is also a clear hierarchical structure.
- \item So what to do with that?
- \end{itemize}
-
-
- \end{frame}
-
-
-
- \begin{frame}\frametitle{Lets pin down NP now!}
-
-
- $\Rrightarrow$ Some ideas what we can do:
- \begin{itemize}
- \item If the NP occurs in the $R_k$, it might also occur in the angular observables! $\Rightarrow$ Lets measure difference in observables like $P_5^{\prime,~\mu} - P_5^{\prime~e}$.
- \item In the $\tau$ sector the NP is competing with a SM tree decay! We could measure: $R(\PLambda_c^{\ast})$\footnote{Please remember that protons kill a lot of background. The main criticism on $R(\PDstar)$ analysis is the background modelling}.
- \item If there exists LU breaking, one cloud also see LFV like: $\PB \to \PK \Plepton \Plepton^{\prime}$, like: $\PBplus \to \PKplus \Pmu \Pe$.
- \item Now playing the devils advocate: Maybe we are remodelling the $\PBzero \to \PKstar \Pmu \Pmu$? One could measure the partial and higher moments in this channel as well in $\PB \to \PK \Pe \Pe$, Collaboration with Roman Zwicky and Greg Cowan~\footnote{My personal opinion, we should keep as much of MoM in UZH as possible.}.
- \item Measure the angular observables of $\PBplus \to K^{*+}_{1}\Pe \Pe$, $\PBplus \to \PKplus \Pe \Pe$ and $\Lambda^{0}_{b}\to \Lambda^{*}\Pe \Pe$ decays.
- \end{itemize}
-
- \end{frame}
-
-
- \begin{frame}\frametitle{Lets pin down NP in Run2 data}
- $\Rrightarrow$ Some ideas what we could do with the full Run2 data:
- \begin{itemize}
- \item Since decays involving $\tau$'s are more sensitive, we could start thinking in modes such as $\PB \to \PK(\PKstar) \Ptau \Ptau$.
- \begin{itemize}
- \item Undergraduate student [Alex Daetwyler] is currently studying the sensitivity for $\PBzero \to \PKstar \Ptau \Ptau$ decays with Run 1 and 2 data.
- \end{itemize}
- \item We should definitely update $\tau \to 3\mu$.
- \item Some more Semi-leptonic measurements!
- \end{itemize}
-
-
- \end{frame}
-
-
- \begin{frame}\frametitle{Summary}
-
-
- \begin{enumerate}
- \item Future analysis will be more challenging!
- \item Run1 data analysis program is still rich in NP searches.
- \item Many analysis are in the pipe line.
- \item We should maximize the coverage of the mentioned topics.
