<p style="margin: 0px; font: 12px Helvetica;">We will have an informal group discussion/brainstorming session on the topic:</p>
<p style="margin: 0px; font: 12px Helvetica; min-height: 14px;"><br>
</p>
<p style="margin: 0px; font: 12px Helvetica;">“The CMB vs. local H0 tension”.</p>
<p style="margin: 0px; font: 12px Helvetica; min-height: 14px;"><br>
</p>
<p style="margin: 0px; font: 12px Helvetica;">Some possible topics to discuss could be:</p>
<p style="margin: 0px; font: 12px Helvetica;">(1) What is the status on internal tensions within CMB data sets now, in the context of H0?</p>
<p style="margin: 0px; font: 12px Helvetica;">(2) What are the possible sources of residual systematics in the local H0 data/analysis?</p>
<p style="margin: 0px; font: 12px Helvetica;">(3) What have been the most interesting attempts to resolve the issue so far?</p>
