Quickest command:

curl -s "https://export.arxiv.org/api/query?search_query=all:YOUR+QUERY&max_results=5" | python3 -c "
import sys, xml.etree.ElementTree as ET
for e in ET.fromstring(sys.stdin.read())[0].findall('{http://www.w3.org/2005/Atom}entry'):
    title = e.find('{http://www.w3.org/2005/Atom}title').text.strip().replace(chr(10),' ')
    print(f'{title[:80]}')
"
